In the draft-eitf-marid-protocol-02.txt in section 2.1 an example is given
of SPF record as
example.com. IN SPF2 "spf2.0/pra +mx +a:colo.examp.e.com/28 -all"
It is noteable that "spf2" part is repeated twice once as the name of the
dns type and second time as a version of the record. I do not believe such
duplication is appropriate because dns record type should be more general
then the version number of the spf record and should not incorporate spf
record version as part of the type name.
To fix it is recomended that all references to SPF dns record type and
examples be changed from "SPF2" to just "SPF" with note in the text that
such dns type records should confront to SPF2.0 or later records. So above
example would change to:
example.com. IN SPF "spf2.0/pra +mx +a:colo.examp.e.com/28 -all"
