All, 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. General Summary: Ready with nits In doing this write up after I wrote my comments, I went and researched the mail archive, and I found Russ Housley's very succinct Gen-Art review: https://mailarchive.ietf.org/arch/msg/gen-art/jBbrcEzrRlSPWGcjEVdvTO41ckQ Specifically the Appendix in the wrong place, the insertion of copyrights in Sections 3.1 and 3.2 Additionally, in Section 2 "Object Description" there are elements for the objects that are marked OPTIONAL or MUST. However, there are many which are not defined either way.  The "assumption" is they are a MUST. If this is true perhaps some text at the beginning of the definitions     "Unless otherwise specified, any element defined is a MUST". tim
