 IMO in WSDL the term MEP is a bit different from SOAP MEP. The
difference is that in SOAP an MEP may span multiple nodes and is
defined from the point of view of a message, whereas WSDL
describes one node and all MEPs used in WSDL must be defined from
the point of view of that one described node.
 In WSDL, other MEPs than one-way and request/response should
IMHO be viewed as orchestration, out of scope of WSDL. Therefore 
we can hardcode these two.
