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.
The Introduction to Predicates Programming Guide states:
"Predicates provide a general means of specifying queries in Cocoa.
The predicate system is capable of handling a large number of
domains, not just—for example—Core Data or Spotlight."
None of the examples in the "Using Predicates" article uses Core Data:

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! ;-)
Please continue to file bugs and enhancement requests, and let us
know what works...
As ever, feedback is useful to know what areas to prioritise.
