This is a warning, not an error, but since the spec explicitly allows this use of if/else, it seems like an inappropriate warning to me. But it's a judgement call. A better way to write this, though, might be if (normalize-space($text) castable as xs:integer) then xs:intefer(normalize-space($test)) div 10 else () liam -- Liam Quin,B https://www.delightfulcomputing.com/ Available for XML/Document/Information Architecture/XSLT/ XSL/XQuery/Web/Text Processing/A11Y training, work & consulting.
