Reading https://www.rfc-editor.org/rfc/rfc8020#section-3.1 
<https://www.rfc-editor.org/rfc/rfc8020#section-3.1>
this should not happen, shouldn't it?

It's possible that `3._domainkey` is a dotted record in the DNS zone for 
`lena.kiev.ua`, and `_domainkey.lena.kiev.ua` isn't set up as its own zone.

Isn't that the usual way to do it?  I certainly didn't create a new zone for 
_domainkey.  Yet, I have (using bind):

Yes, that is as empty non terminals appears.

AFAIK zone is something what has own SOA, and once something has SOA (or any other record) it is not empty anymore ;-)


It'd be easier if SOA records always returned the name of the zone...

If you query for SOA records, you know you queried the zone name when you get it in the answer section rather than the authority section. (Or use +trace).
