Doing it the way you suggest seems to work for LocationPath expressions (http://www.w3.org/TR/xpath#NT-LocationPath), but I can't get it to work for a FunctionCall expression (http://www.w3.org/TR/xpath#NT-FunctionCall). So If you try:
XPath xpath = myElem.createXPath( "bar:baz()" );
or:
XPath xpath = DocumentFactory.getInstance.createXPath( "bar:baz()" );
you get an exception. Is this a bug in the implementation?
