Signaling MEPs

I took an action at the F2F to start a discussion on signaling MEPs  
in SOAP. Currently the SOAP 1.2 HTTP binding supports two MEPs and  
the determination of which is in use can be made by looking at the  
web method property: GET=Response MEP, POST=Request-Response MEP.  
Adding new MEPs to the mix might require a different method to signal  
the MEP: e.g. if we add support for a one-way MEP using HTTP POST,  
how can a receiver tell that its a one-way rather than a request- 
response ?

For HTTP we could consider adding a new HTTP header that specifies  
the MEP in use. Alternatively we could consider adding a new  
parameter to the media type, that would have the advantage of being  
useable in other protocol bindings.

Thoughts ?
