And if you just need the boolean (true()/false()) indicating whether
a sequence has duplicate values -- not needing the values themselves
-- then use the following, slightly adjusted and more efficient
expression:
exists($vSeq[index-of($vSeq,.)[2]][1] )

See this:

It produces all values in the sequence, that occur in it more than once:
$vSeq[index-of($vSeq,.)[2]]

Hello
I have a sequence and want to know whether there are duplicate values in
it.
I came out with the following and think there must be an easy solution.
Any suggestion?
let $sequence :=(1,12,14,17,22,12) return
(count(distinct-values($sequence)) ne count($sequence))
Thanks in advance
Leo
