Ryan,

It is correct that using DAML-S, the WSDL "type" can be extended to
arbitrary DAML-S classes.  This is part of the purpose of the DAML-S
grounding.  Some of this was described in a paper by the DAML-S
Service Coalition that appeared at ISWC2002 (The International
Semantic Web Conference).  A new release of DAML-S is slated for
release at the beginning of August that will contain this grounding.  

Please see 
    http://www.daml.org/services 
for DAML-S papers and release information.

Regards,

Sheila McIlraith
