Please help me with the following problem:
I try to construct the current status of a series of objects along the following simple rules:
- the current status of on object with a certain `identificatie` (id) is the newest version of that object
- except when the newest object has the property `<status>beëindigen</status>` then the object stops existing.
I use a fold-left to proces these rules with a simple function implementing those rules. This gives me unexpected results.
I've reduced the problem to a single stand alone query in which the last object (`obj3`) has the property `<status>beëindigen</status>`.
So I would expect this line: `let $stand4 := fold-left(($obj3, $obj2, $obj1), (), function($stand, $obj) { local:stand-totaal($stand, $obj) })` to give me an empty result as `obj3`has the property <status>beëindigen</status> but I am getting `obj1` as demonstrated in the following stand alone query.
At least another XQuery 3.1 processor that BaseX (tried with SaxonC HE 12.4) also outputs

so it looks, if that is not the result you want, as if the problem is likely in your code.
