I meant to add:

once we start playing with checkpoints vs. external snapshots vs.
hotplug in anger, then knowing WHICH disks existed at the time of a
given checkpoint may prove invaluable to even figure out WHICH disks
need to participate in a given backup operation.  The initial
implementation uses XML (so that adding features can hopefully reuse the
same API, rather than needing yet more one-off API additions), even if
it is currently limited to not playing nicely with snapshots.
