I've been asked to re-review this document on behalf of YANG Doctors.  I'm pleased to say that all of my previous comments have been addressed satisfactorily.  Overall, the document's YANG matter is in good shape.  I did find a few nits, though.

In Section 2.4:

s/has been switched based its/has been switched based on its/

Section Appendix C.4:

s/and adjust the update interval/and adjusts the update interval/

In the description for the eval-expression leaf:

s/the updates are only pushed as/the updates are only pushed at/

In the description for the eval-interval leaf, you call XPath Xpath and you don't mention the name, "eval-expression" whereas you have made this effort in other leafs (yeah, I said leafs).

In the description for the adaptive-period-update notification, you have the same missed "on" that you had in Section 2.4.

In Section 5.1, you have a run-on sentence:

XPath evaluation criteria are applied against a minimal set of data nodes in the data model, the minimal set of data nodes can be advertised...

Maybe, put a period after "data model"?

Those are the nits, but I do have a suggestion.  With respect to the evaluation-interval-unsupported RPC error, I think an example of the supplemental information hint might be nice.
