[Issue 4943] Simplified Proposal for Nested Policy Expression Incompatibility

See: [Issue 4943] Compatibility Matching at Nested Level, Monica
http://www.w3.org/Bugs/Public/show_bug.cgi?id=4943

This integrates two simplified examples allowed for and referenced in WS-SecurityPolicy Sections 8.2 and 8.3. As requested this integrates:

1. Comments in preceding conference call from Asir Vedamuthu
2. Clean copy text and examples (Paul Cotton)

Formats for .doc and .pdf are attached.

Have a safe holiday everyone (for those who have Monday off). Thanks.
