6 * This node represents a single notification.

8 * The signature is mostly identical to that of Sabre\DAV\IFile, but the get() method
9 * MUST return an xml document that matches the requirements of the
10 * 'caldav-notifications.txt' spec.
11 *
12 * For a complete example, check out the Notification class, which contains
13 * some helper functions.
