When an "Organizer" removes a scheduling object resource, the server MUST inspect each "ATTENDEE" property to determine whether to send a scheduling message. The table below indicates the appropriate iTIP method used by the server, taking into account any "SCHEDULE-AGENT" property parameter (see Section 7.1) specified on each "ATTENDEE" property.
+------------------+-------------+
| SCHEDULE-AGENT | iTIP METHOD |

| SERVER (default) | CANCEL |
