The question of where WSDL-S and OWL-S WSDL bindings are mentioned in
the Semantic Annotations for WSDL charter is based on the differences
between the two:

The OWL-S Submission adds the following WSDL markup:
  + message/input@owl-s-parameter identifies OWL-S input or output
    owl-s:Parameter.
  + a new value for binding/encodingStyle identifies an encoding style
    for serializing owl-s:Parameters.
  + operation@owl-s-process identifies an OWL-S atomic process.
and properties attaching a WSDL doc to a WsdlAtomicProcessGrounding and
describing that WSDL:
  wsdlVersion
  wsdlDocument
  wsdlOperation
  wsdlService
  wsdlPort
  wsdlInput &
  wsdlOutput -- WsdlInputMessageMaps describing XSLT
                transformations of I/O messages.
  wsdlInputMessage &
  wsdlOutputMessage

The WSDL-S Submission adds the following WSDL markup:
  + modelReference, I guess can be affixed to any part of the component
    model (pure speculation on my part).
  + xsd:element/schemaMappings transform (XSLT, XQuery...) to "an
    external domain model/ontology", which appears to be more XML.
  + operation/precondition &
    operation/effect in a format opaque to WSDL-S.
  + interface/category links the interface to some taxonomy opaque to
    (not specified by) WSDL-S.

I *think* that the momentum is behind adding modelReferences to WSDL
components. The charter is a test of that hypothesis.
