Tis a paradox indeed. Makes no sense for RPC, yet WSDL is the Web Services
answer to IDL.
The other paradox is that in almost every CORBA development scenario I've been
in, the IDL is the part that gets written by hand, and the language-specific
bindings get generated. In WS land, people want to generate WSDL from Java
I've actually heard the idea of hand-editing WSDL called "nutty".

There you go telling WGs to split languages, again, Paul. ;-)
