can NRTM handle divergent schemas?

If you mean referral-by, it points to mntner handle, mandatory in mntner
object and is part of RPSS (RFC2725) spec.

The core update server (whois_rip, and NRTM is part of it) cares only
about primary keys. It also parses (so they should be RPSL compliant)
and stores attributes that are part of lookup/inverse keys. However,
they are considered as optional by NRTM module. Most of the syntax
checks are done by dbupdate. That's where you need to modify
definitions. But as far as mirroring is concerned, this is not an issue.
