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 issue I have with this document is that the Security Considerations section sais "TBD". At least say something like "This document does not update the Security Considerations of RFC 5031". Perhaps it could be argued that ECRIT URNs that are country-specific makes it more likely that they be targeted for local attacks but that may be a stretch. Cheers Leif
