IMHO that results in a bad structure, because its anot associating
the related info together, eg having an separate element to turn
on/off IPV6, and then listing addresses:
<address family='ipv6'/>
<ip type='ipv6' address='2001:23::2' prefix='48'/>
<ip type='ipv6' address='fe:33:55::33' prefix='64'/>
vs having the direct association
<address family='ipv6'>
<ip address='2001:23::2' prefix='48'/>
<ip address='fe:33:55::33' prefix='64'/>
</address>
the latter removes the redundancy from specifying address family in
multiple places

That's really protocol specific, but it will typically enable some local
address auto-config by the kernel.
