Not on that pony. WSDL isn't capable of doing what you want, not having
adequate descriptive semantics and all that. At best we'll be asking the
publishers of WSDL to abide by the webservices variant of Liskov
substitution. At worst you'll have DLL hell, as Tom rightly pointed out.

DAML-S or FIPA-ACL might be a closer fit. 

But I observe the fun is not in the service description language of
choice, but how we'll have to build the software that can process these
descriptions and act accordingly.
