Dear DM,

I don't have a strong interest in ObsCore, but skimming it
I have one comment.

The name of the new model entries *_xel, designating number of
elements along a given axis, seems a bit strange to me.
If I saw an item named t_nel I'd guess that it means number of
elements, but t_xel sounds mysterious.  Is there a good reason
for this name?  It's not a big deal, and if this is already
written in to existing implementations I'm not seriously suggesting
changing it, but if it's still easy to change it might be worth
