Re: [Gen-art] Gen-ART review of draft-ietf-mext-nemo-v4traversal-07.txt

Hi Brian,

The following appear to me to be used normatively; the absence of an
upper case keyword doesn't prove the absence of a normative reference:

>    [RFC2784]  Farinacci, D., Li, T., Hanks, S., Meyer, D., and P.

>    [RFC2983]  Black, D., "Differentiated Services and Tunnels",
>               RFC 2983, October 2000.

(Sorry about this, it was added at my suggestion and is a downref.)

=> I don't understand how the reference to GRE is a downref. There is no
requirement language for it, it's simply supported if someone needs it.
If you could tell me that then I will understand some of the other downrefs
you refer to.

Also, what do you suggest we do with 2983?

=> Again, I don't see it for 3168, 4213 or 4459. Can you please explain it
for at least a couple of those so I know what you mean? For example, why is
3168 a downref?

=> How can this be a downref??

I think this should indicate how the mobile knows that it's in an IPv4-only
network,
or maybe it should say 'A mobile node that has not been assigned an IPv6
address
by the foreign network...'. Also, there's a missing verb in that sentence.

=> This is explained in section 5.4.4. I forgot to add the verb, will do
that.

Thanks,
Hesham
