Stig,

Thanks for your review.

There is no requirement for the address families to be the same.  Since no
such requirement is stated, I think we're okay.

All smaller values are requested by other internet-drafts, and some are even
deployed.

I don't see any security issues here, beyond what is already mentioned in
the security considerations section.  Do you think there's an issue that
needs further discussion?

I've incorporated your editorial comments.
