Yes I noticed that.  Ok, so the intention is that the url can be
remote in this case.  This makes perfect sense to me.

I should have mentioned the reference, sorry, it's in 8.6.4.1. (My
point here was that the term "configuration subtree" can be
interpreted as a partial config.)

Ok.  But then the validation doesn't give you much more than syntactic
checks.  If you first validate a partial config and then try to apply
it with edit-config, the resulting configuration might be invalid.

So if you do <validate> on the candidate, it will validate the full
config.  And <validate> on inline config will validate a partial
config (e.g. it must allow incomplete relations).  Then the question
is what should <validate> on a local file do?  Should it treat it as a
full config or partial?
