Thx. And good.
In my most recent editor's draft I did purge all use of "message" from the info model (including changing the log to be a packet log). There's no mention of TLVs in the info model. 
https://bhstark2.github.io/babel-information-model/draft-ietf-babel-information-model.html

I'm putting the xml of this into datatracker imminently.
