This Service is used to remove one or more MonitoredItems of a Subscription. When a MonitoredItem is deleted, its triggered item links are also deleted.

Successful removal of a MonitoredItem, however, might not remove Notifications for the MonitoredItem that are in the process of being sent by the Subscription. Therefore, Clients may receive Notifications for the MonitoredItem after they have received a positive response that the MonitoredItem has been deleted.
