This actually doesn't feel contentious to me. The 2 solutions are very similar, and in fact good progress was made at the most recent interim with the 2 authors agreeing to work together. I don't believe I've seen anyone objecting to the concept of a mount whichever form it takes on the mailing list either.

We are simply stating the document needs to track the evolution of this. I don't believe there's anything in this draft that requires an opstate solution be chosen in order to review it. In fact if this were the case since op-state is targeted at *all* yang models, we would have to stop working on all models by this logic. :)

Thanks,
Chris.
