After some readings on SOAP, WSDL, and other languages MEPs, I wonder
how useful it would be to have a common document for them. SOAP works at
the protocol level, WSDL works at the message level, and choreographic
languages work at the web service level. You can hardly compare them.
MEPs are more horizontal than vertical imho.
