Note that simply setting this property to true will not delete the occurrence. Use the XamScheduleDataManager.Remove method to remove an occurrence. Also note that the underlying occurrence will be made into a variance which will be stored in the data source. This is so the the recurring activity knows not to generate the occurrence the next time the application is run.
IsOccurrenceDeleted property's setter is meant to be called by a schedule data connector implementation to specifiy that this occurrence has been deleted when the activity is retrieved from the data source.
