+1 The information needs to be tracked and consolidated. Seems better done by a single person than by many persons duplicating the work, not to mention by zero person (surely someone else is doing the job). This may be less important in LSR though, as we have designated experts which may already do this work. However: -IINM, the designated expert is only appointed when there is a registry. -IMHO there would be value in having the tracking data been public. IANA looks good to me. In theory, github may also work.
That also assumes that code point/flags be tracked -hence allocated- soon enough, rather than been hidden in a draft or specific implementation.

For the existing fields that don’t have registries, there is no burning requirement to go back and define an IANA registry until such time as that flag field is extended. Note that for OSPF, we did add these registries in https://www.rfc-editor.org/rfc/rfc4940.txt (thanks to Kireeti).

The primary issue for me for these fields is not managing the bit assignments but understanding the functionality – and for that I need to look at the document(s) which have that definition. A registry in these cases provides little value and adds process and a possibility for inconsistency. But, I am not expecting that there is anything I can say to change your opinion – nor vice versa. So I appreciate that you have made your POV clear and the reasons for it – and I am not trying to change your opinion. I started this thread because I did not think a change in WG policy should be made solely based on a single document review comment from one individual – even one as highly respected as Alvaro. Thus far we have a handful of opinions – I am hoping more members of the WG will respond to the thread and then we can proceed appropriately.

The WG has been alive for over 20 years, defined many new TLVs with flags fields, and I am not aware of any confusion – so if it ain’t broke don’t fix it. With all due respect Les, you appear to operate with an eidetic memory of all things IS-IS, so I think that you discount the confusion that the rest of us live in. If a field has values defined in two documents, then there’s confusion. Even just finding both is a challenge.
