Changelog and status

Schema changes in the order they appear in the schema:


* Made RequestID optional [See comment to list]

* Defined MessageExtension element [this addresses my issue with the
possible key agreement and Loren's issue about adding in payment
information]

* Added in a status result but no information in the request as yet.
[see bellow]


Editorial issues

Fixed the UseKeyWith schema fragment that had been lost

Fixed the references to query key binding in the definition of locate,
validate.

Fixed the lack of level 2 headings in section 6.


Current work plan:

* Define matching rules for query key binding and template key binding

* It is my belief that these address slava's point 116 as well but may
have to add text in 4.1.1 h as well

* address the security issue raised by abstracting the authenticated
element from an xkrss operation and using it for a different operation.

* address any other residual items from the list bellow that I can get
through

* send draft off to list
