Infoset based rewrite of SOAP Section 4

I've rewritten Section 4 of the SOAP 1.1[1] note in terms of the XML
Infoset[2]. The rewritten section can be found at[3]. My motivation was to
clean up that section, make sure each 'thing' is only defined once and
hopefully make things unambiguous. While doing so I found a couple of
inconsistencies. These are called out in 'ednote' style ( yellow
background ).

Comments, suggestions, flames etc to the usual address.
