I guess it depends on the use case of whether variables having no value is valid or not.
I've a use case where having variables undefined is valid, so I've gone ahead and implemented my own VariableContext for which an empty Document is returned if there is no value available. I guess thanks to the interface, Jaxen users can have behaviour either way.
