I disagree. I think this is a bad idea.
First, how many transports are we expecting? If it is a lot, then that is a
problem as it fractures the EPP ecosystem and the cost of a hundred EPP
transports will be born by the registrars. If it is only 2, this is a waste of
time.
Second, the EPP extensions registry is a Specifications Required registry. That
means anybody can register an EPP transport, which is bad because as we have
seen with the EPP-over-HTTP discussions it is easy to get the security and
transaction semantics wrong. EPP transports need IETF consensus so they get the
proper scrutiny. Allowing people to register EPP-over-REST or EPP-over-Anycast
or EPP-over-FastHTTP or EPP-over-WebSockets or EPP-over-OHTTP or EPP-over-IPsec
or whatever doesn't sound like a good idea.
Third, we should not be encouraging lots of EPP transports. The EPP-over-HTTP
discussion has focused a lot on the costs to the registries but nobody has
mentioned the costs to the registrars. While the registries get to be selective
in which transport they deploy, the registrars have a much higher burden in
that they have to implement most of the transports and EPP XML extensions. New
EPP transports should only be encouraged when the costs to all parties are
weighed.

Hi,
I agree with James that new EPP transports should be registrable EPP

Andy,
I agree that EPP transports are not defined in RFC 3735, which is associated
with EPP XML extensions, but EPP transport extension is a valid form of EPP
extensible as defined in RFC 5730 and there are registrations included in
draft-ietf-regext-epp-https and draft-ietf-regext-epp-quic. I believe its best
that we explicitly support the inclusion of EPP transport extensions to go
along with the EPP XML extension guidelines in RFC 3735. The goal of the EPP
Extension Registry is to ensure that extension specifications are published to
reduce duplicate extensions, which applies to EPP transports. In reviewing the
references to RFC 3735 in draft-ietf-regext-ext-registry-epp, the following is
language that can be updated to provide support for EPP transports explicitly:
1. In Section 1 “Introduction”, modify "Guidelines for extending EPP are documented in RFC 3735 [RFC3735
<https://www.rfc-editor.org/info/rfc3735>]." to "Guidelines for extending EPP transports are
documented in Section 2.1 of RFC 5730 [RFC5730 <https://www.rfc-editor.org/info/rfc5730>] and for extending EPP
XML are documented in RFC 3735 [RFC3735 <https://www.rfc-editor.org/info/rfc3735>]."
2. Section 2.1 “Extension Specification, modify "Note that Section 2.1 of RFC 3735 [RFC3735
<https://www.rfc-editor.org/info/rfc3735>] provides specific guidelines for documenting EPP
extensions." to "Note that Section 2.1 of RFC 3735 [RFC3735
<https://www.rfc-editor.org/info/rfc3735>] provides specific guidelines for documenting EPP XML
extensions."
3. Section 2.1.1 “Designated Expert Evaluation Criteria”, modify "Note that Section 2.1 of RFC 3735
[RFC3735 <https://www.rfc-editor.org/info/rfc3735>] provides specific guidelines for documenting EPP
extensions." to "Note that Section 2.1 of RFC 3735 [RFC3735
<https://www.rfc-editor.org/info/rfc3735>] provides specific guidelines for documenting EPP XML
extensions."
4. Section 4 “Security Considerations”, modify “However, extensions should be evaluated
according to the Security Considerations of RFC 5730 [RFC5730
<https://www.rfc-editor.org/info/rfc5730>] and RFC 3735 [RFC3735
<https://www.rfc-editor.org/info/rfc3735>]."

I have the following feedback items:
>
> 1. In Section 2.1.1, it's recommended change "XML schema and namespace URIs MUST be

"*Defined* XML schema and namespace URIs MUST be registered in the IETF XML Registry using the
procedures described in RFC 3688 [RFC3688]" to make it clear that extensions are not required to
have at least one XML schema and namespace URI, which would not be the case for EPP transport
extensions.

and XML namespace URIs defined in the extension specification MUST be registered
in the IETF XML Registry using the procedures described in RFC 3688 [RFC3688].” We
need to include XML schemas, too, and this is clearer about what “defined” means./*

I am good with the wording, but EPP transports are not extensions according to
RFC 3735. For clarity, that needs to be stated.
Also, RFC 3735 is an informative reference but needs to be a normative
reference.
> 2. In Section 2.2.2, "TLDs: "Any"|<one or more TLD text strings separated by commas>" needs to be modified to "TLDs:
"Any"|*"N/A"|*<one or more TLD text strings separated by commas>" to include the new "N/A" value.

I agree. This is a good change.

This would only require inclusion of the IESG for IETF specifications and not non-IETF / proprietary
specifications.
>

specification records. Another sentence is needed. Perhaps something like this:
“Non-IETF specification records in this registry may only be removed or
deactivated with the approval of the original registrant.”./*
>

This is backwards. The IESG should not be removing registrations created via
IETF consensus. However, the IESG should have the power to remove bad
registrations, such as those wrongly using URIs not under the control of the
registrant, or references that rot and become malware distribution points, or
even court-orders requiring removal.
Also, it could be argued that any registration that is a link to an IETF Internet Draft
or are derived from an IETF Internet Drafts or improperly use an IETF namespace are IETF
specifications. So "non-IETF" is ambiguous.
I suggest the following:
"Registrations not created through IETF consensus may be removed or deactivated with
the approval of the IESG, in consultation with or at the request of the Designated
Experts."
