Re: pkcs7-md5 and pkcs7-sha1 micalg values

After reviewing the draft informational rfc for PKCS #7 at 
http://www.imc.org/draft-hoffman-pkcs-crypt-msg, I believe...

Keeping future S/MIME digest algorithms with the "pkcs7-" prefix is fine, but
will PKCS #7 undergo any changes to allow for additional... 

1. Public-Key algorithms, (elliptic curve, DSA-ElGamal,...) or will S/MIME be 
RSA (asymmetric) forever?

2. ContentEncryptionAlgorithmIdentifier ::=  "for EP2 / as well as RC2"

I propose that the micalg parameter for multipart/signed messages with
the "application/pkcs7-signature" protocol be defined as pkcs7-md5 and
pkcs7-sha1 for the MD5 and SHA-1 digest algorithms respectively.  I
further propose that any future digest algorithms that are supported for
S/MIME keep the "pkcs7-" prefix.

Comments?
