Subject: RE: [ws-rx] NEW ISSUE: What does 'anon' URI mean when used in AcksTo

I think it is incorrect to characterize that WS-Addressing is silent. It just defers the definition to the binding where it belongs to the extent of how the definition is used for WS-Addressing purposes only.
I would be very much in favor of (a) or (b) for our own spec. If (b) can not be coordinated with WS-Addressing wg (we need to do that rather fast due to the timelines of WS-Addressing) , we should definitely explore (a).

Is WS-Addressing's silence on what it means to use the anonymous IRI in the wsa:To header mean that it should be obvious to the reader?  If so, then perhaps we can take the same approach to its use in other places that WS-Addressing is silent as well - for example, AcksTo - and say nothing and assume its obvious to the reader.
