Good point (the elements without a common parent arent siblings gotcha), but I'm not sure that applies here... for example: let $number1 := <number>1</number> let $number2 := <number>2</number> let $number3 := <number>3</number> let $seq1 := ($number1, $number2) let $seq2 := ($number2, $number3) return $seq1 except $seq2 That always has to return <number>1</number>... both sequences refer to same $number2 even it exists in different documents to 1 and 3.
