:-)

I think we already had this discussion on the list and even considered that 
there is no need to include the full long tree when adequate subtrees were 
included to help readers walkthrough a model. The reason was that  subtrees are 
good enough to " to explain things.".

As a contributor, because I fully agree:

" The whole point about tree diagrams is that they should help to
 explain things"

I used to exclusively include only subtrees in the specs with long trees (L2NM, 
L3NM, etc.) with this note: "The full tree diagram of the module can be 
generated using the "pyang" tool [PYANG]. That tree is not included here 
because it is too long (Section 3.3 of [RFC8340]). Instead, subtrees are 
provided for the reader's convenience."

Now as an Editor of the bis, I'm hearing that the WG is not comfortable with 
leaving authors interpreting RFC8340, but a full tree is still needed (in an 
appendix, though).

Cheers,
Med
