+ * Event interface for group content.
+ *
+ * This interface is implemented by the Im and
+ * event object is signalled to registered client observers
+ * through MImContextObserver observer interface.
+ * This event notifies clients about changes in
+ * group content.
+ *
+ * Clients subscribe for this event with
+ * MImGroups::SubscribeImGroupChangeL().
+ *
+ * Im signals this event when:
+ * - New subscribed data is received from protocol.
+ * - Data item data subscription status is updated by
+ *   protocol adaptation.
+ * - When client unsubscribes the data item.
+ * - Im generates initial data notification
+ *   to client automatically after clients subscription,
+ *   when the initial data comes available from protocol.
