## Document History
1. Does the working group (WG) consensus represent the strong concurrence of a
few individuals, with others being silent, or did it reach broad agreement?
This document reached broad agreement.
2. Was there controversy about particular points, or were there decisions where
the consensus was particularly rough?
There was some redesign, but no roughness.
3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If
so, please summarize the areas of conflict in separate email messages to the
responsible Area Director. (It should be in a separate email because this
questionnaire is publicly available.)
No there have been no disagreements about the final state of the document.
4. For protocol documents, are there existing implementations of the contents of
the document? Have a significant number of potential implementers indicated
plans to implement? Are any existing implementations reported somewhere,
either in the document itself (as [RFC 7942] recommends) or elsewhere
Linagora have an implementation, Fastmail have done an evaluation and will implement
soon. Other JMAP implementors have indicated that they intend to support it.
## Additional Reviews
5. Do the contents of this document closely interact with technologies in other
IETF working groups or external organizations, and would it therefore benefit
from their review? Have those reviews occurred? If yes, describe which
reviews took place.
The only other interaction is with the QUOTA extension in EXTRA, and they are
aware of this work and have reviewed it for compatibility.
6. Describe how the document meets any required formal expert review criteria,
such as the MIB Doctor, YANG Doctor, media type, and URI type reviews.
There were no formal expert reviews required.
7. If the document contains a YANG module, has the final version of the module
been checked with any of the [recommended validation tools] for syntax and
formatting validation? If there are any resulting errors or warnings, what is
the justification for not fixing them at this time? Does the YANG module
comply with the Network Management Datastore Architecture (NMDA) as specified
in [RFC 8342]?
There is no YANG.
8. Describe reviews and automated checks performed to validate sections of the
final version of the document written in a formal language, such as XML code,
BNF rules, MIB definitions, CBOR's CDDL, etc.
I checked the JSON sections of the document by feeding them to `jq` and ensuring
that it agreed that they were valid JSON (after manually removing the ... for
elided additional data)
## Document Shepherd Checks
9. Based on the shepherd's review of the document, is it their opinion that this
document is needed, clearly written, complete, correctly designed, and ready
to be handed off to the responsible Area Director?
Yes, the document is ready.
10. Several IETF Areas have assembled [lists of common issues that their
reviewers encounter]. For which areas have such issues been identified
and addressed? For which does this still need to happen in subsequent
11. What type of RFC publication is being requested on the IETF stream ([Best
Current Practice], [Proposed Standard, Internet Standard],
[Informational, Experimental or Historic])? Why is this the proper type
of RFC? Do all Datatracker state attributes correctly reflect this intent?
This document is intended to be a Proposed Standard as it extends an existing
Proposed Standard. It correctly reflects this.
12. Have reasonable efforts been made to remind all authors of the intellectual
property rights (IPR) disclosure obligations described in [BCP 79]? To
the best of your knowledge, have all required disclosures been filed? If
not, explain why. If yes, summarize any relevant discussion, including links
to publicly-available messages when applicable.
The authors have been contacted directly and are unaware of any IPR.
13. Has each author, editor, and contributor shown their willingness to be
listed as such? If the total number of authors and editors on the front page
is greater than five, please provide a justification.
Yes there is only one author, who is willing to be listed.
14. Document any remaining I-D nits in this document. Simply running the [idnits
tool] is not enough; please review the ["Content Guidelines" on
authors.ietf.org]. (Also note that the current idnits tool generates
some incorrect warnings; a rewrite is underway.)
There aren't any issues other than "document 23 days old" which is my fault for
not submitting this earlier.
15. Should any informative references be normative or vice-versa? See the [IESG
Statement on Normative and Informative References].
All the references are normative, and are required to be.
16. List any normative references that are not freely available to anyone. Did
the community have sufficient access to review any such normative
All normative references are to IETF RFCs.
17. Are there any normative downward references (see [RFC 3967] and [BCP
97]) that are not already listed in the [DOWNREF registry]? If so,
No downward references.
18. Are there normative references to documents that are not ready to be
submitted to the IESG for publication or are otherwise in an unclear state?
If so, what is the plan for their completion?
19. Will publication of this document change the status of any existing RFCs? If
so, does the Datatracker metadata correctly reflect this and are those RFCs
listed on the title page, in the abstract, and discussed in the
introduction? If not, explain why and point to the part of the document
where the relationship of this document to these other RFCs is discussed.
This document creates an optional extension to a protocol defined in another RFC.
It doesn't (currently) list that document in the "Updates" section.
20. 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 aspects of the document requiring IANA assignments are
associated with the appropriate reservations in IANA registries. Confirm
that any referenced IANA registries have been clearly identified. Confirm
that each newly created IANA registry specifies its initial contents,
allocations procedures, and a reasonable name (see [RFC 8126]).
The IANA registration looks correct and follows the guidelines for the registry
it is updating.
21. List any new IANA registries that require Designated Expert Review for
future allocations. Are the instructions to the Designated Expert clear?
Please include suggestions of designated experts, if appropriate.
There are no new IANA registrations
