RE: NEW ISSUE: HTTP/HTTPS conflict resolution between policy assertion and WSDL

I wonder if this isn't an example of a more general problem where the policy and the capabilities of the transport conflict. Specifically, if the policy requires a capability that the transport cannot provide or a capability the transport already provides.  Consider a policy that requires reliable messaging. If this policy is used with MQ as the transport what happens? Does the engine recognize that MQ already provides reliable messaging and ignores the assertion or does it try and build reliable messaging on top of MQ? 
All the best, Ashok

Target - WS-Policy Attachment 1.5? Primer?  Proposal - Not sure if I have an absolute proposal, but I'll get the ball rolling: I propose that if there is a conflict, that since presumably the policy authors are a better authority as to what policies should exist for a service, whereas the WSDL might have been automatically generated by a tool or a developer, the policy assertion takes precedence.
