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 updates the handling of digital signatures on Internet-Draft document, defined in RFC5485, for non-ASCII characters in a "text" file. This document has no impact on the security considerations specified in RFC5485, and these same security considerations still apply to this new document. Regards, Rifaat
