 * 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.
