Michael, this might well be related to bug 1387942 (Operators <, <=, >, >= return () not false). But as it occurs with value comparisons in combination with fn:boolean I though it was worth to mention. We run into this as our machine generated queries in specific circumstances include fn:boolean on expressions with "xs:boolean?" as static type. Subsequently we expect a boolean, and not the empty sequence. Consider the following query: for $i in (1,2,3) return boolean((if ($i != 2) then $i else ()) ge 2) It evaluates to false,true where it should be false, false, true. Thanks, Marc
