(7) Source Address Selection of MN
	When host acts as MN, your implementation always select HoA as the
	source address. The source address should be a CoA. 

No, draft-ietf-ipv6-default-addr-select-09.txt Rule 4 says home addresses 
should be preferred, except via a possible API interaction.

Yes, we know.

What we meant was there are some cases that we need to use actual 
address on the device, not HoA.
