This is a statement about what Tor currently supports, not a policy
statement.
You're looking at dnsserv.c for information on adding new types, and
that's a useful, but you'll also need to figure out a wire format for how
to ask an exit node for a non-A/AAAA/PTR resolve, and how to get the reply
back. (See dns.c for the exit-node side of DNS lookup. See eventdns.c in
tor or evdns.c in libevent for the DNS backend.)
For a much better place to start work on these things, see the two mail
threads starting on tor-dev from last January, "Tor and DNS", and
"DNS/DNSSEC resolving in Tor (PoC implementation)."
The "Tor and DNS" thread had a design proposal draft in it, and some
discussion. I don't recall the state of the proposal; it could probably
use some tightening up and another glance. That would be a good place to
start.
