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. It appears that the Security Considerations Section from this document has been copied from RFC 2680. This appears to be appropriate for this document. The document appears to be well written and thorough. I can find no other security concerns in it. Best regards, Chris
