Hi Woj,

I have some comments on this draft.

Regarding Section 5, I am curious why we need the mapping, i.e.
Section 5 if we are doing MAP-E? i.e. NAT44'ed IPv4 packet is
encapsulated in IPv6 using RFC 2473. RFC2473 defines quite in detail
in Section 5 on Tunnel IPv6 Header almost everything needed.

More specific comments: what is the relationship of this draft with
the original MAP-E draft, draft-mdt-softwire-map-encapsulation-00?
That draft described in detail how RFC 2473 would be used which is
missing in draft-ietf-softwire-map-02. OTOH draft-ietf-softwire-map-02
does not even reference draft-mdt-softwire-map-encapsulation-00, why?

Regards,

Behcet
