Dear Basex team, it seems to me that there is a little bug in the FLWOR sort. Code: for $i in 1 to 3 for $j in ('a', 'b', 'c') order by $i descending return    concat($i, $j) Expected output: 3a 3b 3c 2a 2b 2c 1a 1b 1c Actual output: 3c 3b 3a 2a 2b 2c 1c 1b 1a Using the latest stable snapshot. Kind regards, Hans-Juergen
