Right, and all IETF standards are voluntary anyway. Mandating anything as the
exclusive something is never going to fly.
(And as far as the case Fred raised goes, there was very careful chartering
language for ANIMA to ensure that we didn't trample on HOMENET; and there's
also careful language in draft-ietf-anima-prefix-management to show how
it can fit in with DHCPv6-PD. In a nutshell, the autonomic function manages
prefixes as a resource pool, handing them out to devices that can then
delegate them to non-autonomic devices using PD.)
