The mechanism in draft-clemm-netmod-mount primarily mounts remote
datastores into a datastore.

Structural mount focuses on combining *schemas*.  This approach can
support different implementation strategies, where remote mounting
could be one.  However, the structural mount draft does not specify
any such implementation strategies; the idea was that such strategies
could be defined in separate documents (that would reference the
structural mount doc).
