Binding imposes rules on XMLP layer. Further discussion on this that I didn't have time to capture. The doc would be liable to change afterwards as issues become clearer. Maybe we could add a new section that describes alternate view of section 3. Not take them out but move to appendix to clearly mark them as under discussion.
Several people suggest leaving as is.
Discussion around SOAP 1.1 and the role of bindings. RPC is an abstract binding. Lots of discussion around the role of bindings that I didn't capture. What is the view of the subgroup. Would like to understand the approach you are suggesting.
