Thanks for the feedback, Bob.

My thought about non-apex ZONEMD records is that ZONEMD has some similarities 
to SOA.  They both say something about the zone has a whole, and I know some 
software at least rejects zones with a non-apex SOA record.  OTOH, I don't want 
to make things unnecessarily complex...
