It was not clear to me after having read the document that you were 
indeed NOT creating any new MEP. When you list the MEPs supported by the 
reverse binding, I think it would be worth indicating their URIs, so 
that there is no ambiguity about which MEP you are effectively talking 
about.

(It is still unclear to me now whether your "response" MEP is the SOAP 
Response MEP, or some other MEP.)
