Other things Jim requested offline:
- Point to PKIXALG as opposed to CMSALG, which makes sense since this is
the CERT ID.
- Add back in changes from v3 to v3.1, which also makes sense because the
section should not have been removed.

Comments on the draft.
In section 4.4.3, I find the following text confusing:
End-entity certificates contain an extension that
constrains the certificate from being an issuing authority
certificate (see Section 4.4.2).
I believe that this text might be better as it clarifies what
is being stated. I.e. it is not the fact that basic
constraints is being used which actually does the mentioned constraint.
End-entity certificates contain the Key Usage extension which
restraints the end-entity from using the key to perform
issuing authority operations (see
4.4.4)
Also the previous comment (on 3851bis) on key sizes > 4096
should be applied to this document

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 : Secure/Multipurpose Internet Mail Extensions
(S/MIME) Version 3.2 Certificate Handling
Author(s) : S. Turner, B. Ramsdell
Filename : draft-ietf-smime-3850bis-04.txt
Pages : 20
Date : 2008-6-30
This document specifies conventions for X.509 certificate usage by
Secure/Multipurpose Internet Mail Extensions (S/MIME) agents.
S/MIME
provides a method to send and receive secure MIME messages, and
certificates are an integral part of S/MIME agent processing.
S/MIME agents validate certificates as described in RFC 3280bis, the
Internet X.509 Public Key Infrastructure Certificate and CRL
Profile.
S/MIME agents must meet the certificate processing requirements in
this document as well as those in RFC 3280bis. This document
obsoletes RFC 3850.
