Re: [ebxml-msg] Another header v 3.0 option (ws-addressing) withdiscussion and a question.

[Doug Bunting <Doug.Bunting@Sun.COM>]

Dale,

Duplication or overlap of headers in a specific SOAP message certainly 
leaves that message open to conflicts and ambiguity.  For example, would 
the CPA governing the relation between the two endpoints (not the 
intermediaries) need to describe whether the ebXML Messaging headers 
have precedence over other information also available in the messages 
exchanged?  Which is the normative message identifier, the one from 
WS-Reliability or something else?

I am generally not sure where you are heading with this message because 
our specification should remain "composable" with any other headers a 
sender chooses to include, modulo the possible conflicts that arise. 
Such inclusion is not something we can control though we may mention a 
few examples of useful compositions.

With respect to our document, I would strongly recommend we avoid 
reference to work not yet available as a standard.  Reliance on open 
standards has been a strong attribute of the ebXML work to date and is 
not something we should change going forward.

thanx,
	doug
