I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review.  Document editors and WG chairs should treat these comments just like any other last call comments.

With the caveat that I'm not an expert, I've found this document to be READY.

I have found it well-written (those parts that require actual prose) and adequately referenced since it relies heavily on other documents.

Authors, please do remember to remove all non-final text before re-sending.

Thanks!
