Hello from a Waterloo alum.

Your question about WSDL and DAML-S is very interesting but not directly
related to what I meant by the requirement above. There are increasing
numbers of services out there where an XML response contains a URI which
is a reference to another endpoint/node/service/resource/thingee. WSDL
should be able to declare that situation just as IDL can say that the
return from a foo() method call is an object of type Bar. My thought was
that a WSDL file could have port types A and B (or import one or the
other) and say that URIs in the XML in a particular context in a
response from A are interpreted as ports of type B.
