[Issue 2] Inlined proposal v5

Attached.

This proposal consists of taking the inlined proposal v4 produced by 
MikeE [1] and applying it to CD02 rev4. On top of that I have made the 
following changes (based on the last call where we discussed v4):
1) Included a pointer to the appendix examples from section 5.2
2) Missing 2119 statement tags are added.
3) Fixed cross-references and 2119 stmt highlighing.
4) Deleted all the MAY statements that were unnecessary.
5) Replaced lowercase 2119 keywords with appropriate non-keyword substitutes
6) Made the protocol composable with WS-MC without introducing 
additional conformance points.
