Could someone with more clue about that XML stuff than me (Niko

Indeed the bug showed up in XML::XPathEngine. The fix I found though was
not to set the fallback overload, but rather to get findvalue to return
real strings as opposed to XML::XPathEngine::Literal objects. Those
objects are useless outside of the XPath engine, so keeping them around
doesn't seem to do anyone any good. 

Does this make sense?

An updated version is at http://xmltwig.com/module/xml-xpathengine/
The bug will be tested through XML::DOM::XPath.
