Hi Scott,



Not sure how useful this feedback would be but here it is. :)

[SAH] Thanks, much appreciated!



Are we comfortable having this document as Informational? (Knowing RFC 7451 is 
Informational.) Emulating the IETF XML Registry (RFC 3688), could it not be at 
least a BCP if not Standards Track. Key words “MUST”, “SHOULD”, etc help with 
clearer guidance, IMO.

[SAH] I’m comfortable with it as-is, but a change is certainly possible if 
there’s some specific reason that the WG thinks it needs to change.



Noting that the current EPP registry has the “TLDs” column for the domains side 
and it is required information, wonder if that's counter to "It is expected 
that this protocol will have additional uses beyond domain name registration.” 
from RFC 3750, and does it further connote that there can be no non-domain use 
cases for EPP?

[SAH] I don’t think it does. Any non-domain-name-specific extension can 
populate that field with “N/A”. Adding text to make that clear could be helpful.



Section 2.2.4 says: "In addition to entries that become "Inactive" due to a 
lack of implementation, entries for which a specification becomes consistently 
unavailable over time should be marked "Inactive" by the designated expert 
until the specification again becomes reliably available.” Should this 
criterion also be added to the “Status” definition in section 2.2.1 for the 
“Inactive” status part? AFAICT, "The "Inactive" status is used for extensions 
that are not implemented or are otherwise not being used.” doesn’t seem to 
connote specification unavailability.

[SAH] I could add a forward reference from 2.2.1 to 2.2.4 and change the text 
in 2.2.1 to ensure that it’s consistent with 2.2.4. Thanks for the catch.



There are few URIs in the document with the “http” scheme. E.g., 
"http://www.example.com/html/example-epp-ext.txt”. As a better practice, should 
they be changed to the “https” scheme?

[SAH] Yes, they should be changed. I’ll fix that in -02.



Otherwise, the document looks clear to me.



Thanks,

Jasdip

[SAH] Sorry, I'm impatient, so I'm going to be deliberately provocative by 
updating the draft based on the best information that I have in the hope of 
prompting discussion. This version of the draft captures the changes that were 
discussed during the WG last call process and proposed changes based on our 
interim meeting discussion from earlier this week. If I missed anything, or if 
you disagree with anything, please say so. It would also be helpful to note if 
you agree with these changes.
