It seems to me that this needs three columns, like this:

Name	Reference	Type
_tcp	RFC2782		Proto
_udp	RFC2782		Proto
_domainkey	RFC6376	App
_vouch	RFC5516	App

There's a short list of types.  Proto is a protocol that can have any
of the RFC6335 service names as a subnode on SRV or NAPTR records.
App is an application that names TXT records and generally has no
prefixed subnodes, or if it does it's just a handful that are
mentioned in a footnote.  There may be other types, but probably
not many.
