I am all for traditions :) but IMHO they were normative in the other BGP-LS documents because one needs to "normatively" refer to them to know the encoding and understand the meaning of the various fields. I don't see that here. Hope this helps to understand why I asked to re-evaluate this, rest is up to you!

Thanks!
