General Web services in Registry schema

[Paul Harrison]

I really do not see what the problem is with specifying the location of 
the wsdl separately - this is the most flexible way of doing things - it 
works both for services that support ?wsdl and those that do not. We can 
even make the WSDLLocation element optional and have a convention that 
if it is missing you just add ?wsdl to the endpoint.
