Message Waiting Number
2008-05-20
Definition: If present, indicates the number of messages the Acknowledging Application has waiting on a queue for the Requesting Application. These messages would then need to be retrieved via a query. This facilitates receiving applications that cannot receive unsolicited message (i.e., polling).
For example, if there are 3 low priority messages, 1 medium priority message and 1 high priority message, the message waiting number would be 5, because that is the total number of messages.
