Summary:  Ready with minor nits and a (new) downref issue for RFC 2985 

(importation of PKCS #9).  Thanks for addressing my comments on -04 at 

last call.

Major issues:

Minor issues:
Downref issue: idnits identifies three downref issues:

- RFC 5912 was in the previous version and is in the downref registry 

already, so needn't concern us.

- RFC 2985 has been moved from Informative in -04 to Normative in -05.  

Since RFC 2985 is a reproduction of a a external standard, I don't think 

there should be any issue here, but the reference probably ought to be 

normative, and should have been called out in the last call - apologies 

for failing to point this out in my LC review.

-RFC 7107 is only used to flag the definition of the SMI Security for 

S/MIME Attributes registry.  I think this could safely be taken as 


Thus the only real issue is with RFC 2985.

Nits/editorial comments:
Abstract: Must not have references s/[RFC2985]/(RFC 2985)/

s3: Currently s3.1 states in the text that the maximum length of the 

DirectoryString is 255.  ss3.2 and 3.3 have this defined in the ASN.1 

but not in the text.  It would make things consistent if this was stated 

in para 2 of s3:

s/defined as a DirectoryString/defined as a DirectoryString with maximum 

length 255/

s4, last para: s/(see [RFC7030], s3.7 second paragraph)/(see Section 3.7 

of [RFC3070])/
