Rules for intermediaries handling of PIs, whitespace, etc.

During the conference call yesterday, I took an action to start a discussion
of the SOAP 1.2 rules that should be defined for describing what
intermediaries are allowed to do with PIs, lexical space, encodings, etc.

Some items to consider during discussion:
o white space (including line terminators)
o processing instructions
o comments
o encoding
o character reference preservation (or introduction?)
o <foo/> vs. <foo></foo>
o order of attributes
o other items considered outside the Infoset? (see Appendix D of Infoset
spec)

Options include:
1) Allow making lexical changes anywhere
2) Disallow making lexical changes anywhere
3) Disallow lexical changes within a block, allow elsewhere
