XmlDataSource: XPath Workaround For Default Namespaces

The ASP.NET 2.0 XmlDataSource does not provide a way to handle namespaces in the source XML. If your source XML uses namespaces, then you need to use XSLT to remove the namespaces, otherwise you won't be able to create a valid XPath statement that will work with the XmlDataSource. Or do you? (hint: you can do everything in XPath without resorting to XSLT)
