Well, that's what I'm trying to do, but I thought I have to register it with the XPath object. And since the expression won't parse, I don't get an XPath object. I guess I could register the function with the global FunctionContext (XPathFunctionContext.getInstance()), but I haven't tried that yet. And further, I guess I have to register the namespace with some global NamespaceContext as well, and I don't know how to do that...
