RE: Draft agenda: 24 June TAG teleconference (Arch document, WSA update)

Very possible, and if so I certainly apologize.  My note had a very simple 
point, which I think I stand behind:  the sentence I quoted from you said 
(or seemed to me to say) in so many words that SOAP 1.2 had suggested a 
particular existing HTTP binding in WSDL.  It doesn't.  My intent was only 
to eliminate any confusion on that point of fact.  Having skimmed the 
Tag's minutes, I am more or less comfortable with the direction, which I 
take to be: "make sure the WSDL and WSA groups are aware that there are 
potentially issues requiring attention in this area."

Much appreciated :-)

Noah,

I think you misunderstood my points.  The discussion is around what WSD
should do, now that SOAP 1.2 has GET support.  Not even a hint of a
suggestion that XMLP should do more work.

Maybe it's simply a matter of the TAG asking WSD to do a bit of work in 
this
area.  At any rate, I think it's always useful for the TAG to have
discussions about web service architecture.

Cheers,
Dave
