A CMC_message_reference structure is a CMC_counted_string structure containing a message reference, which is the identifier for a message within a message store.

typedef          CMC_counted_string     CMC_message_reference; 
 The CMC implementation only guarantees the message reference to be valid for the life of the session. The message reference is specific to the message store; CMC does not guarantee that the reference has any correspondence to a message identifier used by the underlying messaging system. Only during the current session can the client application expect the message reference to refer to the same message.
