I'm not sure if I agree with this example.  The DNS dissector doesn't
distinguish between different DNS opcodes (query, update, notify) too
well, and thus doesn't properly handle the differences between them.  I'm
not suggesting using multiple dissectors for DNS (or in this case), but I
also wouldn't blindly copy the DNS way too much, since it doesn't go far
enough.

Speaking of which, I'm going to attempt a thorough overhaul of the DNS
code next week.  We'll see how far I get :)
