I assure that the meaning of "attachment" is a mobile node, incorrect ?
So, I guess it would be better to begin the DAD issue with MIPv6
simultaneously.

I guess we have to make a initial charter and milestone which
includes above issues in now. After then, we can add this issue
to the charter again. In order to discuss these issues, we have to
begin two kinds of work, problem statement and requirement
in advance.
