Nopes unless you really want that.
It's all administrative alike and the admin of a zone may put (almost :)
anything in their zones and structure them in any way the want to.

Personally I used to have a separate ipv6.<bla>.<tld> too but I
currently only use that for software not being able to specifically
request the use of IPv6, or ipv4.<bla>.<bla> for IPv4 ofcourse :).

You can easily have in the v6.galaxy:
host-one A
         AAAA 3ffe:1234:5678::xxx:xxx
         A6 mychain ::xxx:xxx
Which will give the host IPv4 (A) and IPv6 (AAAA and/or A6) addresses.
And wether you want to make a separate ipv6.<dom>.<tld> zone is entirely
up to you.

reverse is just PTR :)

Make multiple zones and add those to the

It's probably best if you read
http://www.crt.se/dnssec/bind9/Bv9ARM.ch04.html#AEN980 - IPv6 support in
Bind9, which also covers IPv6 on bind8 for most parts, though afaik
bind8 doesn't support all RR's.
The rest of that document (http://www.crt.se/dnssec/bind9/) will nicely
show you how the rest is done.
