Folks,

I like this new text explaining I-D’s do not qualify as stable documentation 
for “Specification required”, and only IETF documents can use IETF namespaces 
as a summary of our interim meeting.

However, we forgot one use case where we have precedents.
Proprietary EPP extensions that cannot reach consensus as standard can also 
choose the path to publish an informational RFC describing the proprietary 
extension through the individual submission track.
This is stable documentation for a proprietary extension.
This happened for example to RFC9095 (Strict Bundling)
Since this is an IETF document, it did use the IETF schema and namespaces.

To give correct guidance to authors and designated experts:

-Is registration of XML namespaces also required for proprietary extensions 
when they apply for EPP extension registry registrations? The texts is now not 
clear, and registration of XML schema and namespaces might be a hurdle to 
register a proprietary extension. (Remember the goal of the registry is to 
identify proprietary extensions to harmonise into standard extensions even when 
they use incompliant namespaces)
-Are informational RFCs allowed to use IETF  namespaces?

My guidance would be:
-For IETF Standards track EPP extensions, XML schema and
namespace URIs must be registered in the IETF XML Registry using the
procedures described in RFC 3688, These URIs must use the IETF namespaces.
-For proprietary (non-IETF Standards track) EPP extensions, it is encouraged to 
register XML schema and
namespace URIs in the IETF XML Registry.
-Non-IETF namespaces must be used for non-IETF specifications.

Antoin [no-hat]
