In the Note paragraph at the very end of 3.8.3 Order By and Return Clauses, the following two query examples can be found:

let $i := 5,
    $j := 20 * i
return $i, $j

and

let $i := 5,
    $j := 20 * i
return ($i, $j)


In both, the assignment expression for variable 'j' makes use of "i" which as it is now is an element test. I believe this is a typo, and that "$i" was meant.

If it's intended as a element test(which I doubt), I would rename it to avoid confusion with the variable by the same name.
