My approach to such service discovery would be to have WSDL-in-RDF
(or DAML-S, or whatever) as part of the resource description and
use a protocol such as URIQA for discovery, based on the URI of
the service in question.

One then can enrich the service description as required by
applications without having to further muck about with the
infrastructure.

Once agents are able to easily access descriptions, it simply
becomes a matter of vocabulary and semantics -- whether those
descriptions say anything meaningful to the agent in question.
