Michael, with Saxon 8.1, I've the impression there are issues with certain optimizations and how they affect node identity. Consider the following query: declare function local:foo(){<e/>}; "--- expect 1 element ---", let $w := <e/> return (for $v in (1,2,3) return ($w,$w,$w))/. ,"--- expect 3 elements ---", (for $v in (1,2,3) let $w := <e/> return ($w,$w,$w))/. ,"--- expect 9 elements ---", (for $v in (1,2,3) return (<e/>,<e/>,<e/>))/. ,"--- expect 1 element ---", let $w := local:foo() return (for $v in (1,2,3) return ($w,$w,$w))/. ,"--- expect 3 elements ---", (for $v in (1,2,3) let $w := local:foo() return ($w,$w,$w))/. ,"--- expect 9 elements ---", (for $v in (1,2,3) return (local:foo(),local:foo(),local:foo()))/.
