RE: Addressing Requirements for XMLP

Mark,

Thank you for your note setting forth the requirements that WSA is 
suggesting for our continuing work on SOAP [1].  The XMLP workgroup 
is indeed giving these careful attention, and we will be keeping you 
informed of our progress. The purpose of this note is to seek 
clarification on two particular items. 

The first is regarding the second requirement:

"* Delivery of a one-way SOAP Message Exchange Pattern and corresponding

HTTP Binding, such as that proposed by David Orchard [2], and required 
by the Web Services Description Working Group."

Taken literally, this appears to specifically require the development 
of a new binding with one-way semantics, and of course associated HTTP 
binding support. During XMLP discussions some members suggested that 
the requirement was not intended to be taken quite so narrowly, and that

the WSA's needs might also be met by other means.  For example, one 
alternative under discussion would be to revise the existing SOAP 
Request-Response Message Exchange Pattern to make the inclusion of a
SOAP 
envelope optional in the response.

We would very much appreciate early clarification as to whether the 
WSA intends the requirement to be read literally, and thus to
specifically 
require a new one-way MEP, or whether other approaches might also be 
acceptable. 

The second item is a small correction. We believe that item 3 of your 
request erroneously points to
http://lists.w3.org/Archives/Public/xmlp-comments/2005Aug/0000.html
rather than to 
http://lists.w3.org/Archives/Public/xml-dist-app/2005Aug/0011.html

Can you verify this. 


Thx,
Mike Mahan, on behalf of the XMLP WG
