Perhaps the "use-schema" case really is a type of "schema mount", where 
as the "inline" case is a type of "mount".

Perhaps they could/should have entirely separate YANG models to describe 
them.  Possibly in the "use-schema" case could refer to grafting a 
schema into a parent schema rather than mounting it.
