Les,


> IMO, there is no need for registries for the first category. 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.

Regards,
Tony
