It should also be clarify that ArchiveTimeStamp OID was
changed comparing to RFC 3126.
The 'NOTE 1' may be updated as following.

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the S/MIME Mail Security Working Group of
the IETF.

        Title           : CMS Advanced Electronic Signatures (CAdES)
        Author(s)       : J. Ross, et al.
        Filename        : draft-ietf-smime-cades-04.txt
        Pages           : 132
        Date            : 2007-9-5
        
This document defines the format of an electronic signature that can
   remain valid over long periods.  This includes evidence as to its
   validity even if the signer or verifying party later attempts to deny
   (i.e., repudiates the validity of the signature). 

   The format can be considered as an extension to RFC 3852 [4] and 
   RFC 2634 [5], where, when appropriate additional signed and 
   unsigned attributes have been defined.  

   The contents of this Informational RFC amounts to a 
   transposition of the ETSI TS 101 733 V.1.7.3 (CMS Advanced 
   Electronic Signatures - CAdES) [TS101733] and is technically 
   equivalent to it.

NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail
readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
