Current behavior
It seems that the RFC9606 RESINFO RRType 261 is not yet supported.
(I checked version 1.22.0)

Describe the desired feature
Support RESINFO RRType

Potential use-case
For example to be able to use it in local-data, like:

local-data: 'resolver.arpa RESINFO "qnamemin temp-dnssecval infourl=https://example.nl"'

UPDATE:

Probably this would be better given the discussion below:

local-data: 'resolver.arpa RESINFO "qnamemin" "temp-dnssecval" "infourl=https://example.nl"'

(I have left the original wrong line here also, so the discussion below can be better understood)
