RE: Summary: D-AG0011

Hi Suresh,

I was under the assumption that a WS architecture consistent
with the current web would ensure that the two are interoperable. 
Do you see this differently? I itemized the design principals 
and the implementation technologies to be gain consistency. 
Perhaps that is not sufficient to guarantee interoperability, or 
just that a more explicit statement should be made?

Thanks for the comment.

Mike Mahan, Nokia
