New issue: do we want to remove normative wordings in chapter 16 
"Security Consideration"?
-----------------------------------
There are 3 occurrences of RFC normative wordings in conjunction with 
WS-Security in chapter 16 "Security Consideration".  e.g. "RECOMMENDED" 
and "SHOULD".

Do we want to remove those normative wordings?

This decision would have implication to how and whether WS-Security is 
added in references section.

Submitter Proposal:
I tend to think those wordings and references to WS-Security should be 
non-normative. Because, WS-Security usage is orthogonal and optional to 
the main concern of WS-BPEL.

Thanks!
