Historical Access Audit Delete Events

This EventType inherits all Properties of the AuditHistoryDeleteEventType. Their semantic is defined in 5.8.5.

The EventIds reflect the EventIds parameter of the call.

The OldValues identify the value that history contained before the delete. A Server should report all deleted values. It is acceptable for a Server that does not have this information to report a null value. The OldValues will contain an Event with the appropriate fields, each with appropriately encoded values.
