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 authors have not only implemented the changes I suggested but have improved on my suggestions, so I have no further recommendations. Sorry, Anthony, that I missed your email.  I need to set up some sort of alert system to notify me of replies to my reviews.
