[snip]
Not NXDOMAIN. When TLD. is looked up, they should always return NOERROR.
And yield, either (1) the NS records for the TLD, for QTYPE NS or 'ANY'
For other queries TLD. should return NOERROR with Zero RRs in the
answer (Empty response).
A NXDOMAIN response would be declaring that the TLD does not exist.
