I don't think WSDL MEPs are vastly different from XMLP MEPs. In 
my opinion, the description[1] for the SOAP Request-Response MEP 
(Section 6.2.2) could fairly well apply to WSDL's Input-Output 
operation, only if the term SOAP was removed.

Certainly, SOAP's section 6.2.3[2] "State Machine Description" is 
much more detailed and concrete than anything equivalent in WSDL. 
  However, does that really mean that the core concept is not 
identical between the two technologies?



PS. I have just discovered this mailing list...
