Hi Paul.

Sorry to comment late on your review. However, I noticed something in
the draft:

I noticed the following in the draft:

  <binding name="queryHttp" interface="tns:SparqlQuery" 
	    type="http://www.w3.org/2005/08/wsdl/http"
	    whttp:version="1.1">

    <fault name="MalformedQuery" whttp:code="400"/>
    <fault name="QueryRequestRefused" whttp:code="500"/>

    <!-- the GET binding for query operation -->
    <operation ref="tns:query" whttp:method="GET"
	       whttp:inputSerialization="application/x-www-form-urlencoded" />

    <!-- the POST binding for query operation -->
    <operation ref="tns:query" whttp:method="POST" 
	       whttp:inputSerialization="application/x-www-form-urlencoded" />

  </binding>

Can one bind an operation twice? It was not clear from my reading of
the specification whether it was allowed.

If this isn't the case, do we have an issue about this from the DAWG?
If not, we should make this comment to the DAWG, and figure out what
to do here.

As Kendall raised a number of issues, I have lost track of where we
are with accomodating the SPARQL Protocol use of WSDL 2.0.

Regards,

Hugo
