This is the kind of thing that is very difficult to glean from the
documentation as-is - it's easy to miss because IIRC it's not
specifically stated anywhere. NSPredicate and the like appear only in
10.4 (alongside Core Data). I have only ever seen NSPredicate in the
context of Core Data, and so naturally associate the two.
Now that you've drawn that distinction, I guess that NSPredicate
and such use KVC and it does make sense that it would work just fine
apart from Core Data. Thanks, it does clarify a few muddy concepts ...
Thanks to an off-list reply from an Apple Engineer, I now know
that one of the example apps answers my question and a host of
related questions. For those interested, the link is below:

For those of you who are 'in the know', just remember the
confusion Bindings caused. Today there are a number of differently-
angled explanations and demonstrations - mmalc, your own bindings
page helped immensely as it grew, but the first few months were
infuriating. Any concept brand new to any developer (especially when
the documentation is still trying to catch up and it's not clear what
examples will answer specific questions) is bound to cause a flood of
what might seem like brain-dead questions. The specifics, nuts, and
bolts are well-documented it seems, but the overall concepts need
bolstering for sure (this has been discussed many times and I have
personally filed more than a few doc enhancement requests). Patience,
please! ;-)
(Thanks to all involved for the illumination)

There seems to be a common misconception that for some reason if
you (in the general sense) are using Core Data -- especially in
conjunction with bindings -- then any issues you have are related
to Core Data rather than the actual relevant technology. In this
case, the issue is with the use of NSArrayController. Whether or
not you're using Core Data is immaterial.
