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 ASN.1 descriptions of several security-relevant data objects (e.g., CMS messages and S/MIME objects) from the 1988 version of ASN.1 to the 2002 version, without changing the structure expressed by these definitions -- there are no changes to bits on the wire.  The document correctly states that this document itself creates no security issues, because it makes no changes to any protocols (it simply expresses the structure of those protocols in a different, updated syntax).  The only minor concern I have is to be sure that the above claims about the lack of changes are true, i.e., that the ASN.1 syntax is correct.  To ensure this correctness, I would recommend an expert review focused on the ASN.1, if one has not already been done.
