I think that it's what I meant ;=) ...

I should have said "scoping element" rather than "element", but my
understanding is that the PSVI key/keyref tables are both local to the
scoping element and that, therefore, the matching between key/unique and
keyref can only be done at this location.

This is one of the differences with ID/IDREF which tables are local to
the root of the document (the nearest that can be achieved with
key/keyref is to use the document element like shown in this example).

Am I wrong?
