The new tags are so much clearerand more straightforward than "Updates" that the only reason I see foran update tag is due to documents that are in process or the like, sayanything in WG Last Call or a later stage (IETF Last Call for non-WGdrafts). But if people really want, I wouldn't object to a period ofup to a year when new document (those in a state before publicationrequested) could use either Updates or the new tags.Thanks,Donald=============================== Donald E.

We know that Updates _mostly_ works, and I think it would be a mistake to make a knife-switch cutover to disallowing its use. If edge cases arise that the thinking so far hasn't anticipated, it would be needed as a good fallback.

I'm talking about re-publishingwith the same RFC #.More generally, I don't really understand what you think "mandatory"means.Consider two cases:1. We publish an RFC X with a clear mistake. For instance, it allocates   two code points, A and B, and then in the text it says A=1 and   B=2 but in the IANA considerations it says A=1, B=1.2. We publish an RFC X with an algorithm we later determine to be bad.   For instance it says to use a parameter 2 but we later determine   that 2 is bad and 3 would be better.In the former case, I would argue that the RFC correctly read had thecode points A=1 B=2 and thus in order to be conformant with RFC X, youneed to adopt B=2.However, what would you say in the latter case?  Older implementationscontinue to be conformant with RFC X, but just not with RFC Y, whichyou publish later. So, what does "mandatory" mean in this case? Theproblem here, as usual, is the failure to have some way to refer tothe concept of the protocol rather than the concept of the RFC.-Ekr-------------- next part --------------An HTML attachment was scrubbed...URL: <http://www.rfc-editor.org/pipermail/rfc-interest/attachments/20200229/f0257e93/attachment-0001.html>------------------------------Message: 5Date: Sat, 29 Feb 2020 15:12:34 +0100From: Carsten Bormann <cabo at tzi.org>To: Eric Rescorla <ekr at rtfm.com>Cc: Suresh Krishnan <suresh.krishnan at gmail.com>, RFC Interest	<rfc-interest at rfc-editor.org>Subject: Re: [rfc-i] Feedback solicited: Update tags draftMessage-ID: <49F70083-5388-49CA-8A5D-54324C04538C at tzi.org>Content-Type: text/plain;	charset=utf-8On 2020-02-29, at 14:50, Eric Rescorla <ekr at rtfm.com> wrote:> > However, what would you say in the latter case?  Older implementations> continue to be conformant with RFC X, but just not with RFC Y, We would need boilerplate in each RFC that includes potential future amendments.Gr??e, Carsten------------------------------Subject: Digest Footer_______________________________________________rfc-interest mailing listrfc-interest at rfc-editor.orghttps://www.rfc-editor.org/mailman/listinfo/rfc-interest------------------------------End of rfc-interest Digest, Vol 184, Issue 13*********************************************
