WS-Addressing Message Addressing Properties and notificaton

[David Hull <dmh@tibco.com>]

The current definition of Message Action Properties (MAPs) in 
WS-Addressing specifically defines endpoints for replies and faults, and 
doesn't specifically or generally define anything else (as far as I can 
tell).  This is currently an issue before WSA.  I have proposed 
replacing these two special-purpose endpoints with a general set of 
"associated endpoints", tagged by an IRI saying what they mean.  
Naturally, "reply" and "fault" IRIs would be pre-defined, but you could 
also define new roles.

In our context, assuming this proposal or something like it goes 
through, it might make sense to bring the consumer reference endpoint 
into this fold.  Instead of being a WSN consumer reference, it would be 
a WSA "associated endpoint", tagged with a "notification consumer" 
IRI.   There might not be any impact either way to implementors, and 
certainly the messages on the wire would look about the same, but 
suppose any other notification/eventing proposals running around took 
the same step ...
