Hi Scott, all,

Thank you for the effort put into this update.

When reviewing this document, I also reviewed the diff vs. RFC7451 and RFC3735. 
I have a set of comments for which I think a revised version is needed. My full 
review (including editorial suggestions, nits, etc.) can be found at:


  *   pdf: 
https://github.com/boucadair/IETF-Drafts-Reviews/blob/master/2026/draft-ietf-regext-ext-registry-epp-06-rev%20Med.pdf
  *   doc: 
https://github.com/boucadair/IETF-Drafts-Reviews/blob/master/2026/draft-ietf-regext-ext-registry-epp-06-rev%20Med.doc

I'm extracting the main comments fwiw:

# Intended Status

I suggest we change the status to Standard Track as this touches interop.

# Add section with the main changes since RFC7451

The document already list some changes but some main changes are not reflected 
there (e.g., namespace check).

# The document repeats some aspects that are in 8126. I suggest that we can 
avoid repeating or reinterpreting what is in these docs. I would shorten the 
text by having simple citations as appropriate.

An example of interpretation is "Internet-Draft documents do not meet that 
requirement": the practice depends as function of registries. There are 
registries with specification required that accept I-Ds. I think that we just 
need to clearly record what is expected for EPP without making a generic 
statement on 8126.

# Primary/Secondary

CURRENT:
   The IESG should appoint a small pool of individuals (perhaps 3 - 5)
   to serve as designated experts, as described in Section 5.2

I see that the registry has primary/secondary indication. Is that something the 
we need to call out here? What are the expected primary/secondary roles?

# What are the responsibilities of the chairs vs other DEs?

CURRENT:
   The pool should have a single administrative chair
   who is appointed by the IESG.

# I think that we need to make it clear that decisions must be motivated

NEW:
  The decision MUST include justifications that motivated the decision.

# Cover case of CoI for a DE at the end of Section 2.1

I suggest we add a text grabbed from a similar RFC for TLS registries:

NEW:
   In cases where a registration decision could
   be perceived as creating a conflict of interest for a particular
   Designated Expert, that Expert SHOULD defer to the judgment of the other 
Experts.

# Should we say that the name should not overlap with already registered 
extensions?

CURRENT:
   Name of Extension: A case-insensitive, ASCII text string that

# Mismatch with the registry

CURRENT:
   For documents
   that are not RFCs, this will always be "Other".

## I see this not followed in the registry. For example:

Balance Mapping for the Extensible Provisioning Protocol 
(EPP)Informational[http://www.verisign.com/assets/epp-sdk/verisign_epp-extension_balance_v00.html][VeriSign_Inc.<https://www.iana.org/assignments/epp-extensions/epp-extensions.xhtml#VeriSign_Inc.>]AnyNoneActiveNone

## We need to add a new IANA action to update all such entries to follow the 
guidance:

# Consistency with the registry

CURRENT:
   Registrant Name and Email Address: The name and email address of the
   person that is responsible for managing the registry entry.

Should this be changed to "entity" as I see in the registry cases where the 
contact is not a person.

# Active/Inactive

CURRENT:
   The
   "Inactive" status is used for extensions that are not implemented or
   are otherwise not being used.

How this is determined? How this is maintained? Is this purely declarative? 
Should we recommend add a note where a disclosure was made?

# Status Change

CURRENT:
   If the Status value is
   "Inactive", text MUST be included to describe how and when this state
   was reached.

I think this applies for any state transition change. The other transition is 
also interesting to track. Please update accordingly.

# Expectation

CURRENT:
  The required information MUST be formatted consistently using the

Do we expect that formatting issues will lead to reject a request? Do we need 
to say so?

# Modify a registration: CAUTION!

CURRENT:
   Registrations not
   created through IETF consensus can also be removed or deactivated by
   the original registrant, in consultation with the Designated Experts.

How to make sure this change does impact uses by other entities than the 
registrant? There might be operational considerations out there.

# The WG may be concluded

CURRENT:
   in consultation with the current working
   group mailing list focused on the development of EPP extensions.

Please reword to avoid that dependency. Maybe:

NEW:
   in consultation with the working
   group mailing list focused on the development of EPP extensions if such 
working group exists.

# Make sure the guidance is applicable when 3735/regext mailing list/8179 are 
replaced

I suggest to use the following formulations:

* [RFC3735] (or its future replacement),
* regext mailing list (or its successor)
* [BCP79] instead of [RFC8179]

# IANA considerations

## That section should be simplified as we do already have a registry. The 
section should be restricted to requested new IANA actions

## Missing actions

We need at least two actions:

(1)

NEW:
  This document requests IANA to replace the reference of the EPP registry to 
the RFC number to be assigned to this document.

(2)

NEW:
  This document requests IANA to update "Document Status" of all non-RFC 
documents from "Informational" to "Other".

# Missing Operational Considerations Section

I suggest to cover at least the following:

NEW:

X. Operational Considerations

The updates defined in this document are meant to enhance the guidance for 
reviewing EPP extensions (e.g., avoid squatting IETF namespace non IETF 
specification) and thus allows for better interoperability.

Section 3 updates the content of "Document Status" to be compliant with the 
guidance in Section 2. That update does not impact the extension itself. No 
operational issues are induced by that update.

Section 2 includes provisions for modifying and deleting existing registration 
entries by registrants. Such requests MUST NOT be granted if the requested 
action has operational implication on other entities that deploy that extension.

# RFC7451 should be moved form normative to informative references

Let me know if any clarification is needed.

Cheers,
Med
