Greetings,
I noticed that there seems to be an issue with fn:fold-right in BaseX (10.8 beta). When I pass it a sequence of elements, they do not get atomized/accumulated. Example:
let $data := <data> <a>a</a> <b>b</b> <c>c</c> </data> return <test>{ fold-right( $data/*, "", concat(?, ".", ?) ) }</test>
returns: <test/>
The same query in Saxon-HE 11.4 returns: <test>a.b.c.</test>
Best regards, Tim
