Right.  Smart draft.

So it's essentially a vendor extension encoded as either an IP or a domain

I'm still confused.  If I'm not doing PD, am I not allowed to grab
prefixes in a delegated prefix with unknown options?  What should an
implementation that doesn't speak DHCP do -- not even parse the
DELEGATED-PREFIX sub-TLVs (which is what I do currently), or drop any
delegated prefixes with any DHCP options at all?

(I'm actually parsing DHCP, but only the name server bits.)

I'd still like a priority field.  It doesn't seem like it would add much
implementation complexity.

So in order to put a /128 on the loopback I need to do the full prefix
assignment dance.  Please don't change that, I'll let you know how I feel
about it when I'm finished implementing PA.
