Hello, 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 believe this document is ready. I don't have particularly substantive comments to add. The document is very short, describing new profile names for inclusion in the RTP registry. It's short and sweet and to the point; if you were wondering what RFC's derive these new entries, check out section 3. It reminds me of PRDs I have to write engineering that should really be a paragraph or a bulleted list, but instead I'm required to (gracefully) write a full fledged, albeit short, PRD for. :) In any event, the document is well written, clear and precise, and is ready to go. Kind regards, Sarah
