On the second point that you raise, an order by clause was added to Windowing
Use Case in response to Bug #11759.

When we next publish our Use Cases, Q9 will read:

declare variable $seq := fn:doc("person_events.xml");

for sliding window $w in $seq/stream/event
  start  $s when $s/direction eq "in"
  only end  $e when $s/person eq $e/person and
    $e/direction eq "out"
let $person := $s/person
let $workingTime := xs:dateTime($e/@time) - xs:dateTime($s/@time)
group by $person
order by $person
    <time>{ sum($workingTime) }</time>

This order by clause should be added to this test case.
