Actually, thats supposed to be as is.

"chaos" was an alternate network protocol, and "txt" is the type of record.

There is a convention for DNS servers to return version information when you query for a CHAOS (rather than Internet) text record of that type.

EG,

dig chaos txt version.bind

; <<>> DiG 9.7.6-P1 <<>> chaos txt version.bind

DNSMasq supports this convention.
