It is possible if ietf-interface and ietf-routing are part of the same (mounted) schema. If you want to have, e.g., a global list of interfaces and refer to it from a mounted schema (routing instance), then it is not supported by schema mount - and it could hardly be because modules such as ietf-routing do not have the information where they can possibly be mounted.

It is probably necessary, as in the logical-devices example, to include ietf-interfaces in the mounted schema, and handle the relationship between the global and mounted interface list outside the data model.

Ideas how to handle this formally would certainly be appreciated.
