Messaging Service Comment

[mwsachs@us.ibm.com]

Again, sorry about the deadline.  This comment belongs on the work list,
not as a correction to the current version.

Some of the dicussions about interrelations between Reliable Messaging and
transport protocols point up the need to state the assumptions about the
transport function in some manner.  One possibility is some kind of
definition of a conceptual interface between the Messaging Service and the
transport function.  It's fine to say that the messaging service is
agnostic to the transport protocol but in real life, the Messaging Service
run-time must interact with the transport run-time. Design of the messaging
service protocol must be with the understanding of what goes on in the most
likely transports.

Since it is highly likely that an implementation will include both the
messaging service and the transport function, it may be sufficient to
express the interactions as a series of informative notes (or an
informative appendix) rather than as a formal interface definition. The
important point is that the assumptions have to be stated to ensure that
the messaging service and transport function will work together correctly.

Regards,
Marty
