Yes, I think this is correct: the ietf-ospf module imports the ietf-interfaces module, so the latter has to be specified in the YANG library of the mounted schema with "import" conformance. > > Another statement though confuses me , where the argument of > "presence" statement of "shared-schema", > ""The mounted schema together with the 'parent-reference' > make up the schema for this mount point.";" ==> Does This is wrong, parent-reference adds nothing to the schema, only to the accessible tree for XPath evaluations.
