I fail to understand the similarity or more simply why one
would use anonymous IRI for "To". Where would you send the
initial message? /dev/null ;-)
AcksTo EPR using anon IRI is different, it is piggybacking
on the existing channel provided by the binding, similar to ReplyTo and Fault
which corresponds to a kind of "response". Acknowledgement is a kind of
response.

Right - it talks about ReplyTo and
FaultTo but not "To". So, we can either assume that it is implicitly
talking about "To" which means wecan make the same assumption for
AcksTo. Or we can assume that silence on "To" implies something else -
like "its obvious". dunno. Whatever that assumption is, we can probably
carry it over to the AcksTo EPR :-)

RE: [ws-rx] NEW ISSUE:
What does 'anon' URI mean when used in
AcksTo
Hmm. I am wondering whether we are looking at different
versions of the soap binding spec. The current editor's copy [1] has the
following statement in Section 3.5 (Anish was suggesting adding basically a
similar language to our spec in this thread).
{
When
"http://www.w3.org/@@@@/@@/addressing/anonymous" is specified as the address
of the ReplyTo or FaultTo EPR, the underlying SOAP protocol binding provides a
channel to the specified endpoint. Any underlying protocol binding supporting
the SOAP request-response message exchange pattern provides such a channel.
For instance, the SOAP 1.2 HTTP binding[SOAP 1.2 Part 2:
Adjuncts] puts the reply
message in the HTTP response.
}

I saw no mention of what an anonymous wsa:To means
in the soap binding spec - but perhaps I missed it. If not, then they're
silent on it.

Doug,
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).
Cheers,

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.
thanks
