"PD (Automatic Prefix Delegation)" doesn't specify any means to set the prefix pool the routers rely on for delegation, apart from a manual setting.
The DHCPv6 option could be used in this aim, and would be therefore complementary to PD...
Moreover PD also deals with routing protocol negocation, and does then more than just prefix delegation... This point is interesting in so far as the reachability of the subnet(s) corresponding to the delegated prefix must be achieved in a way or another...

"PD (Automatic Prefix Delegation)" is one of the choices.

To solve all the configuration issues with DHCPv6 might be another good
choice, but I guess PD be a minimum requirement for those who want an
automatic prefix delegation mechanism for (for example) IPv6 access
services, and DHCPv6 would be an option for those who want more.
