Subject: Re: [ebxml-msg] Another header v 3.0 option (ws-addressing) withdiscussion and a question.
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 On 23-Oct-03 12:50, Dale Moberg wrote: > Hi, > > We already have identified two new WS- style headers that could take > over some functionality of ebXML Messaging v 2.0 header, wss security > header and wsrm reliability header.
