For example, in my organization, ns1.noc.titech.ac.jp is the
primary for noc.titech.ac.jp and titech.ac.jp.
Sorry, you are right, I probably haven't understood.
A more artificial configuration is
primary1.childzone.parentzone.example.com
is the primary for parentzone.example.com
and
primary2.childzone.parentzone.example.com
is the primary for childzone.parentzone.example.com
