(6) Describe any specific concerns or issues that the Document Shepherd
has with this document that the Responsible Area Director and/or the IESG
should be aware of? For example, perhaps he or she is uncomfortable with
certain parts of the document, or has concerns whether there really is a

No one has threatened an appeal.
(11) Identify any ID nits the Document Shepherd has found in this
document. (See http://www.ietf.org/tools/idnits/ and the Internet-Drafts
Checklist). Boilerplate checks are not enough; this check needs to be
This document has a normative references to Informational RFC 6979 and
Informational RFC 8017, which is not already in the downref registry.
See the response to question (15) below.
(12) Describe how the document meets any required formal review criteria,
such as the MIB Doctor, media type, and URI type reviews.
(13) Have all references within this document been identified as either
normative or informative?
Yes, the references are divided into normative and informative.
(14) Are there normative references to documents that are not ready for
advancement or are otherwise in an unclear state? If such normative
references exist, what is the plan for their completion?
All normative references are already published.
(15) Are there downward normative references references (see RFC 3967)?
If so, list these downward references to support the Area Director in the
Last Call procedure.
This document has a normative reference to Informational RFC 8017.
I am quite surprised there is not a previous downref to PKCS#1 v2.2.
I observe that PKCS#1 v2.1 (RFC 3447) is already in the downref
registry. Please call out the normative reference to RFC 8017 in the
IETF Last Call, and then add RFC 8017 to the downref registry.
This document has a normative reference to Informational RFC 6979.
Cryptographic algorithms are often specified in Informational RFCs,
and that is the case here. Please call out the normative reference
to RFC 6979 in the IETF Last Call, and then add RFC 6979 to the
(16) Will publication of this document change the status of any existing
RFCs? Are those RFCs listed on the title page header, listed in the
abstract, and discussed in the introduction? If the RFCs are not listed
in the Abstract and Introduction, explain why, and point to the part of
the document where the relationship of this document to the other RFCs is
discussed. If this information is not in the document, explain why the
WG considers it unnecessary.
Publication of this document will not change the status of any other
(17) Describe the Document Shepherd's review of the IANA considerations
section, especially with regard to its consistency with the body of the
document. Confirm that all protocol extensions that the document makes
are associated with the appropriate reservations in IANA registries.
Confirm that any referenced IANA registries have been clearly identified.
Confirm that newly created IANA registries include a detailed
specification of the initial contents for the registry, that allocations
procedures for future registrations are defined, and a reasonable name
for the new registry has been suggested (see RFC 5226).
One ASN.1 module identifier needs to be assigned by IANA. In
addition, it is worth noting that NIST will assign the needed
algorithm identifiers once the document is approved.
(18) List any new IANA registries that require Expert Review for future
allocations. Provide any public guidance that the IESG would find useful
in selecting the IANA Experts for these new registries.
No new IANA registries are needed.
(19) Describe reviews and automated checks performed by the Document
Shepherd to validate sections of the document written in a formal
language, such as XML code, BNF rules, MIB definitions, etc.
ASN.1 is used. I compiled the module in Appendix A. It has one
easily corrected error that does not cause the compiler to produce
an error or warning, and the authors have agreed to correct it
along with any concerns raised during IETF Last Call.
In the ASN.1 module, in several places
