Maybe I'm just being naive, but there's a particular point in our
discussion at the f2f about WSRF/EPR [1] (two or three pages down,
search for 'declaring the prefixes') which seems to me to offer a pretty
clean solution (to the problem of accommodating EPRs to WebArch),
namely using qnames as URI parameters to convey EPR parameters, e.g.

  
 http://example.com/fabrikam/acct?wsaw:InterfaceName=fabrikam:Inventory

as the URI equivalent of the EPR (example 2.1 in [2]):

  <wsa:EndpointReference
    xmlns:wsa="http://www.w3.org/2005/03/addressing"
     xmlns:fabrikam="http://example.com/fabrikam">
   <wsa:Address>http://example.com/fabrikam/acct</wsa:Address>
   <wsa:Metadata
       xmlns:wsdli="http://www.w3.org/2004/08/wsdl-instance"
       wsdli:wsdlLocation="http://example.com/fabrikam http://example.com/fabrikam.wsdl">
     <wsaw:InterfaceName>fabrikam:Inventory</wsaw:InterfaceName>
   </wsa:Metadata>
  </wsa:EndpointReference>

I'm not _sure_ this example works, because I can't be sure what the
WSDL for the presumed service is -- it would have to bind the wsaw and
fabrikam prefixes. . .

Thoughts?
