Hi, I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The document is ready to me. I do have though a generic question I regularly ask to myself - regarding the reference to place. My current thinking is that there are usually more than one reference that would be useful to place. Typically, there is a reference that creates the code point in this case, 7153, 8955, 8955, some references are updating the registry (this document) and in some cases, some references are deprecating the usage of the code point - mostly for crypto. I do not think we have clear guidance on which reference to place. In my opinion more than one reference could be placed. I am wondering if there are any thoughts on this. Yours, Daniel
