If you do this, then you'll need an explicit element to turn on / off IPv4 or IPv6 addressing for the inteface as whole. ie to stop the automatic addition of a link-local address.
That should be stated explicitly, not implied by having an empty <address/> tag.
By having the container, for each family, the prescense or not of the container can define whether that address family is enabled for that inteface.
What would 'enabling an address family for an interface' do ? Whatever it does should probably be stated explicitly. The one argument for <address> tags is that it makes it cleaner to bundle addressing info like <ip> and routing info, to make sure that the user doesn't specify ipv6 routes for an interface without ipv6 addresses.
