+/**
+ * Adds caldav notification support to a backend.
+ *
+ * Note: This feature is experimental, and may change in between different
+ * SabreDAV versions.
+ *
+ * Notifications are defined at:
+ * http://svn.calendarserver.org/repository/calendarserver/CalendarServer/trunk/doc/Extensions/caldav-notifications.txt
+ *
+ * These notifications are basically a list of server-generated notifications
+ * displayed to the user. Users can dismiss notifications by deleting them.
+ *
+ * The primary usecase is to allow for calendar-sharing.
