IMO, it's well defined if it's self-descriptive.  WSDL, WS-Policy,
RDF, etc.. won't help as a descriptive framework if what is being
described is entirely proprietary, e.g. proprietary operations,
proprietary data formats, proprietary QoS descriptions, ... 
Self-descriptive means everything is standardized.
