Summary: PF or PF/TIJAH: querying constructed elements
Initial Comment:
Using Aug2009 branch (compiled about a month ago, but seems to persist on
recently compiled Aug2009 code):
The bug was actually found by Eugen. The following query:
(for $query in fn:doc("x")/kaas
let $coll := collection("aap")
let $qid := tijah:query-id($coll, $query)
for $res in tijah:nodes($qid)
return <beer><aap>{$res/text()}</aap></beer>)/aap
fails to compile. The error is:
$ pf test.xq
looking for col: item19, ty: 0x1 in function do_reduce (line 9708)
environment looks like:
col: iter18, type: 0x1, mvar->name: a0016
col: item19, type: 0x200000, mvar->name: a0018
col: item19, type: 0x100000, mvar->name: a0017
fatal error: column 'item19' with type '0x1' not found in environment

It seems to be related to PF/TIJAH, but I'm not completely sure.
The query does not fail when rewriting it to an attribute:
(for $query in fn:doc("x")/kaas
let $coll := collection("aap")
let $qid := tijah:query-id($coll, $query)
for $res in tijah:nodes($qid)
return <beer><aap noot="{$res/text()}"/></beer>)/aap/@noot
