Right, that makes sense.  I don't like putting it in the SOAP layer.  In
essence, the "service URI" is like the CPS, and that should be part of
the request and/or response.

Yeah, because of general soap auth issues (ws-security, whatever w3c
creates, etc), I prefer to allow folks to put a signature into the
request.  But from an implementation, that's harder, so overall I'm
kinda neutral.  I *DO* like the idea of having a single signed message,
for later "dispute resolution" handling.

I think SOAP 1.2 is pretty much done, as far as XKMS is concerned. 
There is some flailing about for the SOAP RPC Encoding, which isn't
appropriate here, and there's some discussion of the HTTP binding, but
the action items and open issues are really hardcore nitty-gritty
things.  The group is already starting to poll for when vendors will
commit to shiping 1.2 implementations.  SOAP 1.2 be mostly-frozen (i.e.,
CR state) well before we need it to be.
