I personally would put A and AAAA for the same name. Otherwise I guess 
there is a risk the resolver using only IPv4 will query for A RR for 
ns1.ipv6.example.com, which of course will not exist.

A and AAAA should use the same namespace.

I think the same is true for any service which uses domain names when 
addressing services. One use in the example below ns1.example.com as 
the domain name for the nameserver for example.com, and that is true 
regardless of what transport you use. Similar rules should be true for 
HTTP, SMTP etc.
