Yes, it's an amusing one. It's the first time I have ever come across a
useful way of using a filter expression where the predicate evaluates to an
integer that's variable, ie. a function of the context item.

I quite like the fact that this generalizes. 

$vSeq[index-of($vSeq,.)[$i]]

produces a list of the (distinct) values in $vseq that have at least $i
occurrences.
