RIPE DB domain object

    Some mandatory entries should become optional (i.e. can be missing):
     - zone-c (zone contact(s)) when the domain is not a zone
     (technically: it has no SOA RR), for instance MX only domains
     have no zone contacts.
At last... Good!
    
    Some important entries should be redefined:
     - nserver (name servers): the new syntax should be:
     (*) name [ (address)+ ]
     with a star for unpublished (secondary) name servers,
What's the use of that??? Do you really see a domain
registrar chasing each and every subdomain in search
for unpublished nameservers? The term "unpublished"
is already a clear indication that it shouldn't be
listed....

     fully qualified domain name of the name server and
     the list of the IP addresses of the name server.
Either one should do, so it should be name|address
