There's already one RR type with a hypenated name (NSAP-PTR).

I've looked for, but can't find, a formal grammar for the <type> field
in master file syntax.

That said (and given the existence of NSAP-PTR) if your lexer doesn't
already treat a hyphen as a legal character in a token rather than as a
token in its own right, that's probably already a bug.
