Remarks
Some AFDataPipe data sources (including PIPoint objects and AFAttribute objects configured with a PI Point data reference)
will send a AFDataPipeRangeDeletedEvent instance to provide the time range that has been removed.
Note that a Refresh action is sent so clients handling only single event changes will know to purge their cache.
