Jim,
1. I was just following the conventions for SHA-1. I take it you're
suggesting we should break with those conventions?
Yes we break with that convention.
2. I copied the last paragraph in 3.2 from RFC 4055 section 5.
These need to be kept as is, we pulled this forward from somebody else who
messed it up. We can't change this.

Sean,
1. Implenations MUST have absent parameters for SHA-2 --
there is no reason to allow anything else to run. I won't
dispute the MUST read with NULL parameters however much I
would like to. The defect does not really apply
as plenty of time has passed and this is a new algorithm. The only
exception to this appears to be in OAEP and PSS where the
parameters are explicitly defined as being required.
2. Why allow for optional parameters on the signature
algorithms for rsa - not permitted for sha-1WithRSAEncryption.

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 : Using SHA2 Algorithms with
Cryptographic Message
Syntax
Author(s) : S. Turner
Filename : draft-ietf-smime-sha2-08.txt
Pages : 10
Date : 2008-9-26
This document describes the conventions for using the Secure Hash
Algorithm (SHA) message digest algorithms (SHA-224, SHA-256, SHA-
384,
SHA-512) with the Cryptographic Message Syntax (CMS). It also
describes the conventions for using these algorithms with CMS and
the
Digital Signature Algorithm (DSA), Rivest Shamir Adleman
(RSA), and
Elliptic Curve DSA (ECDSA) signature algorithms.
