[cddlm] WS-Addressing to drop Reference Properties

[Steve Loughran]

Interesting development over in W3C land: WS-Addressing no longer has 
reference properties, thanks to the unrelenting efforts of 
Savas-the-subversive, and others: 
http://www.w3.org/2002/ws/addr/wd-issues/#i001

This is interesting because the current "modeling stateful resources 
with web services" paper says "a WS-Resource qualified endpoint puts its 
state identifier in the wsa:ReferenceProperties element". Now it can't; 
the state identifier has to be encoded in the URL itself, as with 
classic stateful URLs like IMdB movie links, RDF identifiers, etc, etc. 
So wsa is more aligned with W3C and less with WSRF.

This is not really our problem, we just have to make sure that we use 
terms like "WS-Resource qualified endpoint" without specifying what that 
exactly that means, and wait for the WS-RF definitions to catch up. It 
actually has a nice side-effect operations wise; as all EPRs are now 
just URLs, you can always paste the URL into a web browser and get a 
status page, 404 error, whatever -but something that is good when 
fielding remote bug reports.

I dont know what the implications for the WSDL are,
