22.2 Messaging Quality of Service

   The Messaging module contains the IDL that the programmer uses to define Qualities of Service specific to CORBA messaging.

   Note – Except where defaults are noted, this specification does not state required default values for the following Qualities of Service. Application code must explicitly set its ORB-level Quality of Service to ensure portability across ORB products.
