As best I can tell, it must be either 1 or 3, and is presumably is
implementation-dependent which.  On the one hand, for evaluation purposes it
doesn't matter since evaluating against {x, y, z} is totally redundant when
also evaluating against {y}.  OTOH, allowing 3 makes it's esxposure
implementation dependent if that (those) component(s) is (are) hooked into a
PSVI or other application-visible place.  (I'm not going to claim expertise in
the intricacies of "extreme PSVI" without more searching than I want to do
right now.)  I thought that the WG had prescribed 1, but I'm not clever enough
to read that into the spec as it stands now.
