Yes, I intentionally omitted this in order not to overload the
readers, nevertheless anyone who tries the five problems will
naturally notice this generalization.
Is:
for $d in distinct-values($seq) return $d[count($seq[. eq $d]) ge $i]
equivalent? I think it is, and probably a lot more efficient,
although it is longer.
I can't see how to avoid the for expression...
