Does anyone on the WG agree with Mark here?  Does anyone interpret Noah
Mendelsohn's comment to XMLP as implying what Mark seems to think it
implies?  I think [not wearing my chair hat] that a SOAP message delivered
with POST, PUT, or carrier pigeon should  have the same semantics.  

I'd like to drain this trout pond.  I propose making sure that the glossary
definition of "protocol independence" includes the concept that a Web
service invocation has the same effect irrespective of the protocol or
protocol-level features used to transmit it, and to action the editors to
use Dave Orchard's  discussion of "visibility" in the document and glossary
where appropriate.

That way we can move on, and Mark or whomever can raise a formal issue that
we will record and address for consideration by others later in the W3C
process.  Of course, if someone on the WG wants to discuss this further, we
can do that.

I'm sure this will be seen as another sign of "the management" exerting
schedule, but I think of it as just taking down the "Gone Fishin'" sign off
the office  door. :-)
