[wsia][wsrp][wsia-wsrp-joint-interfaces] re-annotated requirement s doc

Sorry not to have gotten this out sooner...basically attempted to capture
the state of the debate for the requirements as of last night.  Latest (not
final) edits indented in bold (helps to turn off change tracking if you're
looking at the Word doc).
