Hi,

I think this draft is looking good. A couple of points:

> 2.1.3.  Deprecated addresses in the policy table
> 
>    IPv4-compatible IPv6 address is deprecated.  [RFC4291] IPv6 site-
>    local unicast address is deprecated.  [RFC3879] Moreover, 6bone
>    testing address was [RFC3701] The issue is how we treat these
>    outdated addresses.

The sentence about 6bone is incomplete. I think the answer for 6bone
is that 3ffe::/16 is just another reserved unicast prefix now, but it
may be allocated one day. So why list it at all? It's just part of
2000::/3 now.

The only exception might be 3ffe:831f::/32. That was used as an
experimental Teredo prefix, so it might be wise to list it with low
precedence. But even that could cause a problem many years from now,
when 3ffe::/16 is assigned as unicast space.

For the other deprecated addresses, listing them with low precedence
seems correct.

> 5.1.  Normative References

It seems to me that very few of the references are actually normative.
Most of them should be moved to "Informative".
