I think you meant RFC 2181 but that does not change what is legal
in a hostname. You can store hostnames in the DNS. You can store
other things in the DNS. This is like writing on paper. RFC 2181
is about what are legal keys in the DNS.
hostname != domain name
_spf.yandex.ru is not a legal hostname whether it is written on
paper, in crayon on the driveway, in chalk on a blackboard or when
it is stored in the DNS.
_spf.yandex.ru is not a legal hostname alias for another hostname.
