NEW ISSUE: Change optional example from MTOM to security (Guidelines  
and Primer)

Bug 3952 - <http://www.w3.org/Bugs/Public/show_bug.cgi?id=3952>

Target: Guidelines, primer

Justification:

MTOM is a very bad example for optionality since it raises  
ambiguities depending on message flow.Bbest practices might suggest  
using different endpoints for with and without MTOM. Reason is that  
MTOM assertion mandates usage of MTOM on both requests and responses,  
so request without MTOM is ambiguous, is it a message that wouldn't  
naturally use MTOM, is it in error, or does it signal desire not to  
use MTOM.

Proposal:
Change to example using WS-SecurityPolicy, for example that messages  
optionally may need timestamp using Timestamp assertion.

Test: review guidelines and primer.

regards, Frederick
