Reviewer: Tim Chown Review result: Has Issues Hi, 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. The draft defines an "issuemail" property tag that can be included in a Relevant Resource Record Set to indicate that the domain is requesting Certification Authorities restrict the issue of certificates based on the result of processing the tag as described in the document. The draft is clearly written and includes appropriate examples of the use of the tag. I believe the draft is Ready to progress.
