i033: reusing wsdli:wsdllocation

I took an action to propose how to reuse wsdli:wsdlLocation to hint as
to where one might find an appropriate service description.

wsdlLocation is defined in the WSDL 2.0 spec [1] but that section does
not actually constrain it identification of WSDL 2.0 documents (this is
probably unintentional, and we should confirm with the WSDL WG.)

The examples in Rebecca's mail [2] (as interpreted by me):

<wsa:EndpointReference
    xmlns:my="http://example.com/mynamespace">
  ...
  <wsa:service>my:Service</wsa:service>
  <wsa:serviceDescription>
    http://example.com/fetch/the/wsdl/here
  </wsa:serviceDescription>
  ...
</wsa:EndpointReference>

can thus be rewritten as:

<wsa:EndpointReference
    xmlns:my="http://example.com/mynamespace"
    xmlns:wsdli="http://www.w3.org/@@@@/@@/wsdl-instance"
    wsdli:wsdlLocation="http://example.com/mynamespace
                        http://example.org/fetch/the/wsdl/here">
  ...
  <wsa:service>my:Service</wsa:service>
  ...
</wsa:EndpointReference>

My proposal is to:
1) Confirm (or lobby) with the WSDL WG that wsdli:wsdlLocation applies
to WSDL 1.1 as well as WSDL 2.0.
2) Show examples in our spec using wsdli:wsdlLocation on
wsa:EndpointReference.

I'm not sure we'd need a wsa property [description(s)], the wsdlLocation
implies that and I think cleanly composes without a property but I don't
see real harm in defining that property either.  If a property is
useful, perhaps it should be defined in the WSDL spec so it is
associated with the syntax more closely.
