The question here is "Are the publicly accessible NS servers in a
consistent functional state?". The goal is not to validate the data.

So, I suppose the "object" you're trying to watch is the "NS" consistency state of the zone. So yes, you'd alert against the zone name such as what you've shown in your hosts.cfg example.

Testing this would essentially do

dig example.com ns
<grab the list of dns servers>
dig @ns1 example.com soa
dig @ns2 example.com soa
<compare soa records to see if they are identical>

Xymon can do the DNS lookups, all that is needed is to cook up the necessary data analysis.

I think this should be a separate test from the normal "dns" column?
