Re: [netext] I-D Action: draft-ietf-netext-pd-pmip-05.txt

Hi,

I noticed the addition of a new option to PBU: Delegated Mobile Network
Prefix Option.

Arguably a new option in PBU may make sense if the existing RFC5213 Home
Network Prefix Option can not be reused to communicate this 'delegated'
prefix.

But it has a GRE key in it... should we all implement it (even if set to 0)?

Could the DMNP option be present in PBU and the HNP option absent?

Also I notice the addition of IPv4 (DMNP can be IPv4 or IPv6).  Is there
a particular form of IPv4-in-IPv6 encapsulation that is preferred?
