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.

This document has a security considerations section that references several other documents and adds a comment on additional information disclosure.  I looked at the referenced security considerations and they are quite extensive.  My main complaint would be that the reader has to go trace through the trail of documents to track down the security considerations, however the referenced documents contain material which is essential in implementing this document.  

I think this document is ready.
