The definition of "data model" in RFC 7950 is too informal. What is meant by it
in the schema mount document is basically "datastore schema" as defined in RFC
8342. Perhaps a better term would just be "schema".

No, "schema tree" is only for a single module, accrding to the definition in
7950. What is meant here is a schema of multiple modules, as defined by YANG
library.

This was my original idea, but maybe it is better to use "schema" or "datastore
schema" for the latter.
