Two last call comments:

Draft-ietf-smime-rfc2630bis-05.txt

In section 5.3 the discussion of the signedAttrs field the following
sentence occurs "Each SignedAttribute in the SET MUST be DER encoded."
There are two problems with the statement.  First there is no
SignedAttribute field or structure.  Second, this statement does not
make sense.  It should either be "Each AttributeValue" or "The
SignedAttributes set MUST be DER encoded for tranmission as well as
signature processing." 

Working group straw poll at the IETF meeting prefered the second
alternative.

Draft-ietf-smime-cmsalg-06.txt

In section 6.1 there is a discussion that CMS implemenations must accept
parameters as both NULL and absent for parsing.  There should be a
matching statement that CMS implementations SHOULD generate NULL
parameters.  [This could be absent as well, I don't currently have any
preference as to which option is chosen.]
