Allow namespace objects to be passed in to StartElementLiteral() and AddAttributeLiteral(). This makes it much easier to put things into the default namespace.

Allow multiple different default namespaces inside XML::Genx::SAXWriter. Previously you would get a "Duplicate Prefix" error.
Make the tests work in perl 5.6.1. Not sure when I broke this..
