 For the PMIP6 case, we wrote an I-D:

 http://tools.ietf.org/id/draft-korhonen-dime-pmip6-03.txt

 which hopefully should become a WG item.

 And as you will see, we have some exchange between LMA and AAA but right before
we have some exchanges between MAG and the AAA.

 So even in this case, I wouldn't say that it is only Prefix
Delegation Authorization which
is needed but a whole application to do AAA in the PMIPv6 case.
