Summary: XQ: Duplicates when not using intermediate result
Initial Comment:
We've found a bug that causes results to be returned multiple times.
I've been able to reduce the data and query to manageable proportions, see
files below.
When you run the xquery script, it will return 8, while 4 is expected.
If the lines in the result that are commented are included, the correct result
is given, while all they do is count the number of items produced in
intermediary stages.

let $input1 := (doc("file:///path_to_test_xml")//test)
let $hits1 := (doc("file:///path_to_test_xml")//[EMAIL PROTECTED])
let $input2 := ($input1 intersect $hits1)
let $input3 := for $raw in $input2 where not(empty(for $t in $raw//* return
$t)) return $raw
let $hits3 := (doc("file:///path_to_test_xml")//[EMAIL PROTECTED])
let $result := ($input3 intersect $hits3)
return element result {
(:element input1 {count($input1)} ,
element hits1 {count($hits1)} ,
element input2 {count($input2)} ,
element input3 {count($input3)} ,
element hits3 {count($hits3)} ,:)
element result {count($result)}
}

found the problem (incorrect property inference for intersect) -- as soon
as I'm allowed to check in again I will fix it.

Hi Lefteris,
Maybe have a short look at this one. It is quite likely that Jan will have
to look at it..
