Re: [wsrf] WS-Addressing submitted to W3C as input

Good question.

But taking a step back, I am not sure what EPR is trying to do -- is it 
trying to provide a referencing mechanism for a Web service/endpoint or 
provide such a reference with additional bag of coordination/context 
related data. Both seem like a useful thing to do, but my concern is 
that EPR construct does not provide a clear separation of the two. I.e., 
provide a referencing mechanisms at the base layer and build on it by 
providing a way to including coordination/context related data (thru ref 
properties/ref parameters). It seems like architecturally it makes sense 
to separate the two.
