Reviewer: Carlos Martínez Review Result: Ready 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. I found the document easy to read. The specification is clear and examples in Appendix C are of real help for us who are not experts in the area. I believe the document to be ready.
