+    { id: 'id2', content: 'Immutable content', mutable: false },
+  ],
+};
+
+
+editor.DataSources.add(dataSource);
+
+const ds = editor.DataSources.get('my-datasource');
+ds.getRecord('id1').set('content', 'Updated content'); // Succeeds
+ds.getRecord('id2').set('content', 'New content'); // Throws error
+```
