+
+    <!--
+        Name: Human-readable, localized, short name for the object.
+
+        Normally you need to set this for objects which do not have a labelled-by
+        relation.  Consider a widget to select RGB colors by setting three sliders.  The
+        names for the sliders would be "Red", "Green", "Blue", respectively, or
+        translations to application's locale.  The names would be unnecessary if each
+        slider had a labelled-by relation to corresponding labels visible in the user
+        interface.
+
+        In general, something is missing from your application if an object that can be
+        interacted with has no Name or a labelled-by relation.
+    -->

+
+    <!--
+        Description: Human-readable, localized description of the object in more detail.
+
+        While the Name property is meant to be a short string that screen readers say
+        during normal navigation, the Description property is for when the user asks for
+        more detail.
+    -->
+    <property name="Description" type="s" access="read"/>

+    <!--
+        Parent: Accessible parent object of the current object.
+
+        The (so) is a string for the application name, and an object path.
+
+        Null parent: If the object has no parent (e.g. the application's root object is
+        being queried), return "" for the application name name and "/org/a11y/atspi/null"
+        for the object path.
+
+        Root object: An application must have a single root object, called
+        "/org/a11y/atspi/accessible/root".  All other objects should have that one as
+        their highest-level ancestor.

+
+    <!--
+        Locale: Unix locale for the current object.
+
+        For an application, this may be the locale for the language that the application
+        shows in its user interface.
+
+        For a document being shown in an application, or a paragraph within a document,
+        the locale may refer to that object exclusively.  For example, an application may
+        be showing itself in English ("en"), but it may be used to display a document in
+        Spanish ("es").  In the latter case, a screen reader will want to know that it
+        should switch to Spanish while reading the document.
+    -->
+    <property name="Locale" type="s" access="read"/>
+
+    <!--
+        AccessibleId: application-specific identifier for the current object.
+
+        You can use this to give a special id to an object to use in tests, for example,
+        "my_widget".  Note that there is no way to directly find an object by its id; your
+        test program may have to recursively get the children to find a specific id.  This
+        is because accessible objects can be created dynamically, and they do not always
+        correspond to a static view of an application's data.

+        (see below), and an array of references to accessible objects to which that
+        relationship applies.  Each element in the inner array is a (so) with a string for
+        the application name, and an object path.
+
+        Each relationship between objects (possibly one-to-many or many-to-one) allows
+        better semantic identification of how objects are associated with one another.
+        For instance, the ATSPI_RELATION_LABELLED_BY relationship may be used to identify
+        labelling information that should accompany the accessible name property when
+        presenting an object's content or identity to the end user.  Similarly,
+        ATSPI_RELATION_CONTROLLER_FOR can be used to further specify the context in which
+        a valuator is useful, and/or the other UI components which are directly effected
+        by user interactions with the valuator. Common examples include association of
+        scrollbars with the viewport or panel which they control.
+
+        Relation types - these are the enum values from AtspiRelationType in atspi-constants.h:
+
+        0 - ATSPI_RELATION_NULL: Not a meaningful relationship; clients should not
+            normally encounter this value.
+
+        1 - ATSPI_RELATION_LABEL_FOR: Object is a label for one or more other objects.
+
+        2 - ATSPI_RELATION_LABELLED_BY: Object is labelled by one or more other
+            objects.
+
+        3 - ATSPI_RELATION_CONTROLLER_FOR: Object is an interactive object which
+            modifies the state, onscreen location, or other attributes of one or more
+            target objects.
+
+        4 - ATSPI_RELATION_CONTROLLED_BY: Object state, position, etc. is
+            modified/controlled by user interaction with one or more other objects.
+            For instance a viewport or scroll pane may be ATSPI_RELATION_CONTROLLED_BY
+            scrollbars.
+
+        5 - ATSPI_RELATION_MEMBER_OF: Object has a grouping relationship (e.g. 'same
+            group as') to one or more other objects.
+
+        6 - ATSPI_RELATION_TOOLTIP_FOR: Object is a tooltip associated with another
+            object.
+
+        7 - ATSPI_RELATION_NODE_CHILD_OF: Object is a child of the target.
+
+        8 - ATSPI_RELATION_NODE_PARENT_OF: Object is a parent of the target.
+
+        9 - ATSPI_RELATION_EXTENDED: Used to indicate that a relationship exists, but
+           its type is not specified in the enumeration.
+
+        10 - ATSPI_RELATION_FLOWS_TO: Object renders content which flows logically to
+             another object. For instance, text in a paragraph may flow to another
+             object which is not the 'next sibling' in the accessibility hierarchy.
+
+        11 - ATSPI_RELATION_FLOWS_FROM: Reciprocal of ATSPI_RELATION_FLOWS_TO.
+
+        12 - ATSPI_RELATION_SUBWINDOW_OF: Object is visually and semantically considered
+             a subwindow of another object, even though it is not the object's child.
+             Useful when dealing with embedded applications and other cases where the
+             widget hierarchy does not map cleanly to the onscreen presentation.
+
+        13 - ATSPI_RELATION_EMBEDS: Similar to ATSPI_RELATION_SUBWINDOW_OF, but
+             specifically used for cross-process embedding.
+
+        14 - ATSPI_RELATION_EMBEDDED_BY: Reciprocal of ATSPI_RELATION_EMBEDS. Used to
+             denote content rendered by embedded renderers that live in a separate process
+             space from the embedding context.
+
+        15 - ATSPI_RELATION_POPUP_FOR: Denotes that the object is a transient window or
+             frame associated with another onscreen object. Similar to ATSPI_TOOLTIP_FOR,
+             but more general. Useful for windows which are technically toplevels
+             but which, for one or more reasons, do not explicitly cause their
+             associated window to lose 'window focus'. Creation of an ATSPI_ROLE_WINDOW
+             object with the ATSPI_RELATION_POPUP_FOR relation usually requires
+             some presentation action on the part of assistive technology clients,
+             even though the previous toplevel ATSPI_ROLE_FRAME object may still be
+             the active window.
+
+        16 - ATSPI_RELATION_PARENT_WINDOW_OF: This is the reciprocal relation to
+             ATSPI_RELATION_POPUP_FOR.
+
+        17 - ATSPI_RELATION_DESCRIPTION_FOR: Reciprocal of ATSPI_RELATION_DESCRIBED_BY.
+             Indicates that this object provides descriptive information about the target
+             object(s). See also ATSPI_RELATION_DETAILS_FOR and ATSPI_RELATION_ERROR_FOR.
+
+        18 - ATSPI_RELATION_DESCRIBED_BY: Reciprocal of ATSPI_RELATION_DESCRIPTION_FOR.
+             Indicates that one or more target objects provide descriptive information
+             about this object. This relation type is most appropriate for information
+             that is not essential as its presentation may be user-configurable and/or
+             limited to an on-demand mechanism such as an assistive technology command.
+             For brief, essential information such as can be found in a widget's on-screen
+             label, use ATSPI_RELATION_LABELLED_BY. For an on-screen error message, use
+             ATSPI_RELATION_ERROR_MESSAGE. For lengthy extended descriptive information
+             contained in an on-screen object, consider using ATSPI_RELATION_DETAILS as
+             assistive technologies may provide a means for the user to navigate to
+             objects containing detailed descriptions so that their content can be more
+             closely reviewed.
+
+        19 - ATSPI_RELATION_DETAILS: Reciprocal of ATSPI_RELATION_DETAILS_FOR. Indicates
+             that this object has a detailed or extended description, the contents of
+             which can be found in the target object(s). This relation type is most
+             appropriate for information that is sufficiently lengthy as to make
+             navigation to the container of that information desirable. For less verbose
+             information suitable for announcement only, see ATSPI_RELATION_DESCRIBED_BY.
+             If the detailed information describes an error condition,
+             ATSPI_RELATION_ERROR_FOR should be used instead.  Since 2.26.
+
+        20 - ATSPI_RELATION_DETAILS_FOR: Reciprocal of ATSPI_RELATION_DETAILS. Indicates
+             that this object provides a detailed or extended description about the target
+             object(s). See also ATSPI_RELATION_DESCRIPTION_FOR and ATSPI_RELATION_ERROR_FOR.
+             Since 2.26.
+
+        21 - ATSPI_RELATION_ERROR_MESSAGE: Reciprocal of ATSPI_RELATION_ERROR_FOR.
+             Indicates that this object has one or more errors, the nature of which is
+             described in the contents of the target object(s). Objects that have this
+             relation type should also contain ATSPI_STATE_INVALID_ENTRY when their
+             GetState method is called.  Since: 2.26.
+
+        22 - ATSPI_RELATION_ERROR_FOR: Reciprocal of ATSPI_RELATION_ERROR_MESSAGE.
+             Indicates that this object contains an error message describing an invalid
+             condition in the target object(s). Since: 2.26.

+
+    <!--
+        GetRole:
+
+        Gets the accessible role that the current object represents.  Roles make it
+        possible for various UI toolkits to expose their controls to assistive
+        technologies (ATs) with a standard interface, regardless of toolkit.  For example,
+        a widget that acts like a conventional push button (appears unpressed; presses
+        when acted upon; invokes a certain action when pressed) can expose an
+        ATSPI_ROLE_PUSH_BUTTON role.
+
+        Role values - these are the enum values from AtspiRole in atspi-constants.h:
+
+        0 - ATSPI_ROLE_INVALID: A role indicating an error condition, such as
+            uninitialized Role data.
+
+        1 - ATSPI_ROLE_ACCELERATOR_LABEL: Object is a label indicating the keyboard
+            accelerators for the parent.
+
+        2 - ATSPI_ROLE_ALERT: Object is used to alert the user about something.
+
+        3 - ATSPI_ROLE_ANIMATION: Object contains a dynamic or moving image of some
+            kind.
+
+        4 - ATSPI_ROLE_ARROW: Object is a 2D directional indicator.
+
+        5 - ATSPI_ROLE_CALENDAR: Object contains one or more dates, usually arranged

+             and optionally accepts user input, but whose purpose is not to solicit user
+             input. Thus ATSPI_ROLE_TEXT is appropriate for the text view in a plain text
+             editor but inappropriate for an input field in a dialog box or web form. For
+             widgets whose purpose is to solicit input from the user, see ATSPI_ROLE_ENTRY
+             and ATSPI_ROLE_PASSWORD_TEXT. For generic objects which display a brief amount
+             of textual information, see ATSPI_ROLE_STATIC.
+
+        62 - ATSPI_ROLE_TOGGLE_BUTTON: A specialized push button that can be checked or

+             otherwise clip a larger object or content renderer to a specific
+             onscreen viewport.
+
+        69 - ATSPI_ROLE_WINDOW: A top level window with no title or border.

+
+        74 - ATSPI_ROLE_RULER: An object which describes margins and tab stops, etc.
+             for text objects which it controls (should have
+             ATSPI_RELATION_CONTROLLER_FOR relation to such).
+
+        75 - ATSPI_ROLE_APPLICATION: An object corresponding to the toplevel accessible
+             of an application, which may contain ATSPI_ROLE_FRAME objects or other
+             accessible objects. Children of objects with the ATSPI_ROLE_DESKTOP_FRAME role
+             are generally ATSPI_ROLE_APPLICATION objects.
+
+        76 - ATSPI_ROLE_AUTOCOMPLETE: The object is a dialog or list containing items
+             for insertion into an entry widget, for instance a list of words for
+             completion of a text entry.
+
+        77 - ATSPI_ROLE_EDITBAR: The object is an editable text object in a toolbar.
+
+        78 - ATSPI_ROLE_EMBEDDED: The object is an embedded component container.  This
+             role is a "grouping" hint that the contained objects share a context
+             which is different from the container in which this accessible is
+             embedded. In particular, it is used for some kinds of document embedding,
+             and for embedding of out-of-process component, "panel applets", etc.
+
+        79 - ATSPI_ROLE_ENTRY: The object is a component whose textual content may be
+             entered or modified by the user, provided ATSPI_STATE_EDITABLE is present.
+             A readonly ATSPI_ROLE_ENTRY object (i.e. where ATSPI_STATE_EDITABLE is
+             not present) implies a read-only 'text field' in a form, as opposed to a
+             title, label, or caption.
+
+        80 - ATSPI_ROLE_CHART: The object is a graphical depiction of quantitative data.
+             It may contain multiple subelements whose attributes and/or description
+             may be queried to obtain both the  quantitative data and information about
+             how the data is being presented. The ATSPI_LABELLED_BY relation is
+             particularly important in interpreting objects of this type, as is the
+             accessible description property. See ATSPI_ROLE_CAPTION.
+
+        81 - ATSPI_ROLE_CAPTION: The object contains descriptive information, usually
+             textual, about another user interface element such as a table, chart, or
+             image.
+
+        82 - ATSPI_ROLE_DOCUMENT_FRAME: The object is a visual frame or container which
+             contains a view of document content.  Document frames may occur within
+             another Document instance, in which case the second document may be
+             said to be embedded in the containing instance.  HTML frames are often
+             ATSPI_ROLE_DOCUMENT_FRAME:  Either this object, or a singleton descendant,
+             should implement the org.a11y.atspi.Document interface.
+
+        83 - ATSPI_ROLE_HEADING: The object serves as a heading for content which
+             follows it in a document. The 'heading level' of the heading, if
+             availabe,  may be obtained by       querying the object's attributes.
+
+        84 - ATSPI_ROLE_PAGE: The object is a containing instance which encapsulates a
+             page of information. ATSPI_ROLE_PAGE is used in documents and content which
+             support a paginated navigation model.
+
+        85 - ATSPI_ROLE_SECTION: The object is a containing instance of document content
+             which constitutes a particular 'logical' section of the document.  The
+             type of content within a section, and the nature of the section division
+             itself, may be obtained by querying the object's attributes.  Sections
+             may be nested.
+
+        86 - ATSPI_ROLE_REDUNDANT_OBJECT: The object is redundant with another object in
+             the hierarchy, and is exposed for purely technical reasons.  Objects of
+             this role should be ignored by clients, if they are encountered at all.
+
+        87 - ATSPI_ROLE_FORM: The object is a containing instance of document content
+             which has within it components with which the user can interact in order
+             to input information; i.e. the object is a container for pushbuttons,
+             comboboxes, text input fields, and other 'GUI' components. ATSPI_ROLE_FORM
+             should not, in general, be used for toplevel GUI containers or dialogs,
+             but should be reserved for 'GUI' containers which occur within document
+             content, for instance within Web documents, presentations, or text
+             documents.  Unlike other GUI containers and dialogs which occur inside
+             application instances, ATSPI_ROLE_FORM containers' components are
+             associated with the current document, rather than the current foreground
+             application or viewer instance.
+
+        88 - ATSPI_ROLE_LINK: The object is a hypertext anchor, i.e. a "link" in a
+             hypertext document.  Such objects are distinct from 'inline' content
+             which may also use the Hypertext/Hyperlink interfaces to indicate
+             the range/location within a text object where an inline or embedded object
+             lies.
+
+        89 - ATSPI_ROLE_INPUT_METHOD_WINDOW: The object is a window or similar viewport
+             which is used to allow composition or input of a 'complex character',
+             in other words it is an "input method window".
+
+        90 - ATSPI_ROLE_TABLE_ROW: A row in a table.
+
+        91 - ATSPI_ROLE_TREE_ITEM: An object that represents an element of a tree.

+             to be displayed or composed either in plain text or HTML.
+
+        97 - ATSPI_ROLE_COMMENT: An object found within a document and designed to
+             present a comment, note, or other annotation. In some cases, this object
+             might not be visible until activated.
+
+        98 - ATSPI_ROLE_LIST_BOX: A non-collapsible list of choices the user can select from.

+              hotspots, where each hotspot can be activated resulting in the loading of
+              another document or section of a document.
+
+        101 - ATSPI_ROLE_NOTIFICATION: A transitory object designed to present a
+              message to the user, typically at the desktop level rather than inside a
+              particular application.
+
+        102 - ATSPI_ROLE_INFO_BAR: An object designed to present a message to the user
+              within an existing window.
+
+        103 - ATSPI_ROLE_LEVEL_BAR: A bar that serves as a level indicator to, for
+              instance, show the strength of a password or the state of a battery. Since: 2.8
+
+        104 - ATSPI_ROLE_TITLE_BAR: A bar that serves as the title of a window or a

+
+        110 - ATSPI_ROLE_LANDMARK: A region of a web page intended as a
+              navigational landmark. This is designed to allow Assistive

+
+        111 - ATSPI_ROLE_LOG: A text widget or container holding log content, such
+              as chat history and error logs. In this role there is a
+              relationship between the arrival of new items in the log and the
+              reading order. The log contains a meaningful sequence and new
+              information is added only to the end of the log, not at arbitrary
+              points. Since: 2.12
+
+        112 - ATSPI_ROLE_MARQUEE: A container where non-essential information
+              changes frequently. Common usages of marquee include stock tickers
+              and ad banners. The primary difference between a marquee and a log
+              is that logs usually have a meaningful order or sequence of
+              important content changes. Since: 2.12
+
+        113 - ATSPI_ROLE_MATH: A text widget or container that holds a mathematical
+              expression. Since: 2.12
+
+        114 - ATSPI_ROLE_RATING: A widget whose purpose is to display a rating,
+              such as the number of stars associated with a song in a media
+              player. Objects of this role should also implement
+              the Value interface. Since: 2.12
+
+        115 - ATSPI_ROLE_TIMER: An object containing a numerical counter which
+              indicates an amount of elapsed time from a start point, or the time

+
+        116 - ATSPI_ROLE_STATIC: A generic non-container object whose purpose is to display
+              a brief amount of information to the user and whose role is known by the
+              implementor but lacks semantic value for the user. Examples in which
+              ATSPI_ROLE_STATIC is appropriate include the message displayed in a message
+              box and an image used as an alternative means to display text.
+              ATSPI_ROLE_STATIC should not be applied to widgets which are traditionally
+              interactive, objects which display a significant amount of content, or any
+              object which has an accessible relation pointing to another object. The
+              displayed information, as a general rule, should be exposed through the
+              accessible name of the object. For labels which describe another widget, see
+              ATSPI_ROLE_LABEL. For text views, see ATSPI_ROLE_TEXT. For generic
+              containers, see ATSPI_ROLE_PANEL. For objects whose role is not known by the
+              implementor, see ATSPI_ROLE_UNKNOWN. Since: 2.16.
+
+        117 - ATSPI_ROLE_MATH_FRACTION: An object that represents a mathematical fraction. Since: 2.16.
+
+        118 - ATSPI_ROLE_MATH_ROOT: An object that represents a mathematical expression
+              displayed with a radical. Since: 2.16.
+
+        119 - ATSPI_ROLE_SUBSCRIPT: An object that contains text that is displayed as a
+              subscript. Since: 2.16.
+
+        120 - ATSPI_ROLE_SUPERSCRIPT: An object that contains text that is displayed as a
+              superscript. Since: 2.16.
+
+        121 - ATSPI_ROLE_DESCRIPTION_LIST: An object that represents a list of term-value
+              groups. A term-value group represents an individual description and consist
+              of one or more names (ATSPI_ROLE_DESCRIPTION_TERM) followed by one or more
+              values (ATSPI_ROLE_DESCRIPTION_VALUE). For each list, there should not be
+              more than one group with the same term name. Since: 2.26.
+
+        122 - ATSPI_ROLE_DESCRIPTION_TERM: An object that represents a term or phrase
+              with a corresponding definition. Since: 2.26.
+
+        123 - ATSPI_ROLE_DESCRIPTION_VALUE: An object that represents the description,
+              definition, or value of a term. Since: 2.26.
+
+        124 - ATSPI_ROLE_FOOTNOTE: An object that contains the text of a footnote. Since: 2.26.
+
+        125 - ATSPI_ROLE_CONTENT_DELETION: Content previously deleted or proposed to be

+              from reviewers. Since: 2.34.
+
+        127 - ATSPI_ROLE_MARK: A run of content that is marked or highlighted, such as for
+              reference purposes, or to call it out as having a special purpose. If the
+              marked content has an associated section in the document elaborating on the
+              reason for the mark, then an ATSPI_RELATION_DETAILS relation should be used on the mark
+              to point to that associated section. In addition, the reciprocal relation
+              ATSPI_RELATION_DETAILS_FOR should be used on the associated content section
+              to point back to the mark. See the GetRelationSet method. Since: 2.36.
+
+        128 - ATSPI_ROLE_SUGGESTION: A container for content that is called out as a
+              proposed change from the current version of the document, such as by a reviewer of
+              the content. An object with this role should include children with
+              ATSPI_ROLE_CONTENT_DELETION and/or ATSPI_ROLE_CONTENT_INSERTION, in any order, to
+              indicate what the actual change is. Since: 2.36
+
+        129 - ATSPI_ROLE_PUSH_BUTTON_MENU: A specialized push button to open a menu. Since: 2.46

+
+        1 - ATSPI_STATE_ACTIVE: Indicates a window is currently the active window, or
+            an object is the active subelement within a container or table. ATSPI_STATE_ACTIVE
+            should not be used for objects which have ATSPI_STATE_FOCUSABLE or

+            ATSPI_STATE_FOCUSED and ATSPI_STATE_SELECTED respectively.
+            ATSPI_STATE_ACTIVE is a means to indicate that an object which is not
+            focusable and not selectable is the currently-active item within its
+            parent container.
+
+        2 - ATSPI_STATE_ARMED: Indicates that the object is armed.
+
+        3 - ATSPI_STATE_BUSY: Indicates the current object is busy, i.e. onscreen
+            representation is in the process of changing, or the object is
+            temporarily unavailable for interaction due to activity already in progress.
+
+        4 - ATSPI_STATE_CHECKED: Indicates this object is currently checked.
+
+        5 - ATSPI_STATE_COLLAPSED: Indicates this object is collapsed.
+
+        6 - ATSPI_STATE_DEFUNCT: Indicates that this object no longer has a valid
+            backing widget (for instance, if its peer object has been destroyed).
+
+        7 - ATSPI_STATE_EDITABLE: Indicates the user can change the contents of this
+            object.
+
+        8 - ATSPI_STATE_ENABLED: Indicates that this object is enabled, i.e. that it
+            currently reflects some application state. Objects that are "greyed out"
+            may lack this state, and may lack the ATSPI_STATE_SENSITIVE if direct
+            user interaction cannot cause them to acquire ATSPI_STATE_ENABLED.
+            See ATSPI_STATE_SENSITIVE.
+
+        9 - ATSPI_STATE_EXPANDABLE: Indicates this object allows progressive
+            disclosure of its children.
+
+        10 - ATSPI_STATE_EXPANDED: Indicates this object is expanded.
+
+        11 - ATSPI_STATE_FOCUSABLE: Indicates this object can accept keyboard focus,
+             which means all events resulting from typing on the keyboard will
+             normally be passed to it when it has focus.
+
+        12 - ATSPI_STATE_FOCUSED: Indicates this object currently has the keyboard
+             focus.
+
+        13 - ATSPI_STATE_HAS_TOOLTIP: Indicates that the object has an associated
+             tooltip.
+
+        14 - ATSPI_STATE_HORIZONTAL: Indicates the orientation of this object is
+             horizontal.
+
+        15 - ATSPI_STATE_ICONIFIED: Indicates this object is minimized and is
+             represented only by an icon.
+
+        16 - ATSPI_STATE_MODAL: Indicates something must be done with this object
+             before the user can interact with an object in a different window.
+
+        17 - ATSPI_STATE_MULTI_LINE: Indicates this (text) object can contain multiple
+             lines of text.
+
+        18 - ATSPI_STATE_MULTISELECTABLE: Indicates this object allows more than one of
+             its children to be selected at the same time, or in the case of text
+             objects, that the object supports non-contiguous text selections.
+
+        19 - ATSPI_STATE_OPAQUE: Indicates this object paints every pixel within its
+             rectangular region. It also indicates an alpha value of unity, if it
+             supports alpha blending.
+
+        20 - ATSPI_STATE_PRESSED: Indicates this object is currently pressed.
+
+        21 - ATSPI_STATE_RESIZABLE: Indicates the size of this object's size is not
+             fixed.
+
+        22 - ATSPI_STATE_SELECTABLE: Indicates this object is the child of an object
+             that allows its children to be selected and that this child is one of
+             those children that can be selected.
+
+        23 - ATSPI_STATE_SELECTED: Indicates this object is the child of an object that
+             allows its children to be selected and that this child is one of those
+             children that has been selected.
+
+        24 - ATSPI_STATE_SENSITIVE: Indicates this object is sensitive, e.g. to user
+             interaction. ATSPI_STATE_SENSITIVE usually accompanies.
+             ATSPI_STATE_ENABLED for user-actionable controls, but may be found in the
+             absence of ATSPI_STATE_ENABLED if the current visible state of the control
+             is "disconnected" from the application state.  In such cases, direct user
+             interaction can often result in the object gaining ATSPI_STATE_SENSITIVE,
+             for instance if a user makes an explicit selection using an object whose
+             current state is ambiguous or undefined. See ATSPI_STATE_ENABLED,
+             ATSPI_STATE_INDETERMINATE.
+
+        25 - ATSPI_STATE_SHOWING: Indicates this object, the object's parent, the
+             object's parent's parent, and so on, are all 'shown' to the end-user,
+             i.e. subject to "exposure" if blocking or obscuring objects do not
+             interpose between this object and the top of the window stack.
+
+        26 - ATSPI_STATE_SINGLE_LINE: Indicates this (text) object can contain only a
+             single line of text.
+
+        27 - ATSPI_STATE_STALE: Indicates that the information returned for this object
+             may no longer be synchronized with the application state.  This can occur
+             if the object has ATSPI_STATE_TRANSIENT, and can also occur towards the
+             end of the object peer's lifecycle.
+
+        28 - ATSPI_STATE_TRANSIENT: Indicates this object is transient.
+
+        29 - ATSPI_STATE_VERTICAL: Indicates the orientation of this object is vertical;
+             for example this state may appear on such objects as scrollbars, text
+             objects (with vertical text flow), separators, etc.
+
+        30 - ATSPI_STATE_VISIBLE: Indicates this object is visible, e.g. has been
+             explicitly marked for exposure to the user. ATSPI_STATE_VISIBLE is no
+             guarantee that the object is actually unobscured on the screen, only that
+             it is 'potentially' visible, barring obstruction, being scrolled or clipped
+             out of the field of view, or having an ancestor container that has not yet
+             made visible. A widget is potentially onscreen if it has both
+             ATSPI_STATE_VISIBLE and ATSPI_STATE_SHOWING. The absence of
+             ATSPI_STATE_VISIBLE and ATSPI_STATE_SHOWING is
+             semantically equivalent to saying that an object is 'hidden'.
+
+        31 - ATSPI_STATE_MANAGES_DESCENDANTS: Indicates that "active-descendant-changed"
+             event is sent when children become 'active' (i.e. are selected or
+             navigated to onscreen).  Used to prevent need to enumerate all children
+             in very large containers, like tables. The presence of
+             ATSPI_STATE_MANAGES_DESCENDANTS is an indication to the client that the
+             children should not, and need not, be enumerated by the client.
+             Objects implementing this state are expected to provide relevant state
+             notifications to listening clients, for instance notifications of
+             visibility changes and activation of their contained child objects, without
+             the client having previously requested references to those children.
+
+        32 - ATSPI_STATE_INDETERMINATE: Indicates that a check box or other boolean
+             indicator is in a state other than checked or not checked.  This
+             usually means that the boolean value reflected or controlled by the
+             object does not apply consistently to the entire current context.
+             For example, a checkbox for the "Bold" attribute of text may have
+             ATSPI_STATE_INDETERMINATE if the currently selected text contains a mixture
+             of weight attributes. In many cases interacting with a
+             ATSPI_STATE_INDETERMINATE object will cause the context's corresponding
+             boolean attribute to be homogenized, whereupon the object will lose
+             ATSPI_STATE_INDETERMINATE and a corresponding state-changed event will be
+             fired.
+
+        33 - ATSPI_STATE_REQUIRED: Indicates that user interaction with this object is
+             'required' from the user, for instance before completing the
+             processing of a form.
+
+        34 - ATSPI_STATE_TRUNCATED: Indicates that an object's onscreen content
+             is truncated, e.g. a text value in a spreadsheet cell.
+
+        35 - ATSPI_STATE_ANIMATED: Indicates this object's visual representation is
+             dynamic, not static. This state may be applied to an object during an
+             animated 'effect' and be removed from the object once its visual
+             representation becomes static. Some applications, notably content viewers,
+             may not be able to detect all kinds of animated content.  Therefore the
+             absence of this state should not be taken as
+             definitive evidence that the object's visual representation is
+             static; this state is advisory.
+
+        36 - ATSPI_STATE_INVALID_ENTRY: This object has indicated an error condition
+             due to failure of input validation.  For instance, a form control may
+             acquire this state in response to invalid or malformed user input.
+
+        37 - ATSPI_STATE_SUPPORTS_AUTOCOMPLETION: This state indicates that the object
+             in question implements some form of typeahead or
+             pre-selection behavior whereby entering the first character of one or more
+             sub-elements causes those elements to scroll into view or become
+             selected. Subsequent character input may narrow the selection further as
+             long as one or more sub-elements match the string. This state is normally
+             only useful and encountered on objects that implement AtspiSelection.
+             In some cases the typeahead behavior may result in full or partial
+             completion of the data in the input field, in which case
+             these input events may trigger text-changed events from the source.
+
+        38 - ATSPI_STATE_SELECTABLE_TEXT: This state indicates that the object in
+             question supports text selection. It should only be exposed on objects
+             which implement the AtspiText interface, in order to distinguish this state
+             from ATSPI_STATE_SELECTABLE, which infers that the object in question is a
+             selectable child of an object which implements AtspiSelection. While
+             similar, text selection and subelement selection are distinct operations.
+
+        39 - ATSPI_STATE_IS_DEFAULT: This state indicates that the object in question is
+             the 'default' interaction object in a dialog, i.e. the one that gets
+             activated if the user presses "Enter" when the dialog is initially
+             posted.
+
+        40 - ATSPI_STATE_VISITED: This state indicates that the object (typically a
+             hyperlink) has already been activated or invoked, with the result that
+             some backing data has been downloaded or rendered.
+
+        41 - ATSPI_STATE_CHECKABLE: Indicates this object has the potential to
+             be checked, such as a checkbox or toggle-able table cell. Since: 2.12
+
+        42 - ATSPI_STATE_HAS_POPUP: Indicates that the object has a popup
+             context menu or sub-level menu which may or may not be
+             showing. This means that activation renders conditional content.
+             Note that ordinary tooltips are not considered popups in this
+             context. Since: 2.12
+
+        43 - ATSPI_STATE_READ_ONLY: Indicates that an object which is ENABLED and
+             SENSITIVE has a value which can be read, but not modified, by the
+             user. Since: 2.16

+        exists. The string returned should contain localized, human-readable,
+        key sequences as they would appear when displayed on screen. It must
+        be in the format "mnemonic;sequence;shortcut".
+
+        - The mnemonic key activates the object if it is presently enabled onscreen.
+          This typically corresponds to the underlined letter within the widget.
+          Example: "n" in a traditional "New..." menu item or the "a" in "Apply" for
+          a button.
+
+        - The sequence is the full list of keys which invoke the action even if the
+          relevant element is not currently shown on screen. For instance, for a menu
+          item the sequence is the keybindings used to open the parent menus before

+
+        - The shortcut, if it exists, will invoke the same action without showing
+          the component or its enclosing menus or dialogs. Example: "Ctrl+N" in a
+          traditional "New..." menu item.
+
+        Example: For a traditional "New..." menu item, the expected return value
+        would be: "N;Alt+F:N;Ctrl+N" for the English locale and "N;Alt+D:N;Strg+N"
+        for the German locale. If, hypothetically, this menu item lacked a mnemonic,
+        it would be represented by ";;Ctrl+N" and ";;Strg+N" respectively.

+      @short_description: Interface to query accessible objects in bulk.
+
+      The application should expose this interface at the /org/a11y/atspi/cache object
+      path.
+
+      The org.a11y.atspi.Accessible interface has methods like GetChildren and
+      GetChildAtIndex, but these only transfer an object's DBus id.  The caller has to
+      then query the object's properties individually.  Transferring objects one by one and
+      then their properties produces a lot of traffic in the accessibility bus.
+
+      So, this Cache interface can be used to query objects in bulk.  Assistive tech
+      should try to do a bulk query of all the objects in a new window with the GetItems
+      method, and then update them dynamically from the AddAccessible and RemoveAccessible
+      signals.
+
+      FIXME: Does GetItems only get called if an application implements
+      GetApplicationBusAddress?  GTK4 doesn't implement that, but it implements GetItems -
+      does that ever get called?

+
+        Returns: an array with one element for each available object.  Each element's
+        fields are like this:
+
+        - (so): accessible object reference - DBus name and object
+          path.  The rest of the fields refer to this main object.
+
+        - (so): application reference - DBus name and object path.  This is the owner of
+          the main object; the root path of the application that registered via
+          the Embed method of the org.a11y.atspi.Socket interface.
+
+        - (so): parent object reference - DBus name and object path.

+
+                - If it is a control, or a window, return the parent application.
+
+                - If the object has the application role, return a null reference.  FIXME:
+                  atk-adaptor/adaptors/cache-adaptor.c:append_cache_item() returns a

+                  "/org/a11y/atspi/null" for the object path).
+
+        - i: index in parent, or -1 for transient widgets/menu items.  Equivalent to the
+          GetIndexInParent method of the org.a11y.atspi.Accessible interface.
+
+        - i: child count of main object, or -1 for defunct/menus.  Equivalent to the
+          ChildCount property of the org.a11y.atspi.Accessible interface.
+
+        - as: array of names of the interfaces that the main object supports.  Equivalent
+          to the GetInterfaces method of the org.a11y.atspi.Accessible interface.
+
+        - s: human-readable, localized, short name for the main object.  Equivalent to the
+          Name property of the org.a11y.atspi.Accessible interface.
+
+        - u: role.  Equivalent to the GetRole method of the org.a11y.atspi.Accessible interface.

+        "a(so)" instead of "ii" is a list of references to child objects.  The
+        implementation in atspi-misc.c can handle either version, although the intention
+        is to deprecate the code that handles the old version.  Qt still uses this old
+        signature and should be changed to the new scheme (see qspi_struct_marshallers.cpp

+        RegisterKeystrokeListener:
+        @listener: path of object to be notified when the following keys are pressed
+        @keys: array of (key_code, key_sym, key_string, unused)
+        @mask: modifier mask in X11 style (see Xlib.h)
+        @types: mask of press/release; see the description below.
+        @mode: struct of flags (synchronous, preemptive, global), see the description below.
+
+        The @types can be a mask of the following:
+
+          * KEY_PRESS   = 1 << 0
+          * KEY_RELEASE = 1 << 1
+
+        Note that Orca always passes (KEY_PRESS | KEY_RELEASE).
+
+        The @mode is composed of three flags (see AtspiKeyListenerSyncType):
+
+          * synchronous: Events are delivered synchronously, before
+            the currently focused application sees them.  If false,
+            events may be delivered asynchronously, which means in some
+            cases they may already have been delivered to the
+            application before the AT client receives the notification.
+
+          * preemptive: (called CANCONSUME in AtspiKeyListenerSyncType)
+            Events may be consumed by the AT client.  Requires the synchronous flag to be set.
+
+          * global: (called ALL_WINDOWS in AtspiKeyListenerSyncType)
+            Events are received not from the application toolkit layer,
+            but from the device driver or windowing system subsystem.
+
+        Returns: boolean indicating whether the operation was successful.  This is always
+        TRUE for non-global listeners (c.f. @mode), and may be FALSE for global listeners
+        if the underlying XGrabKey() failed (see spi_dec_x11_grab_key).
