XML wizardery by Wayne Graham

I've been using xml files both as config and controller files (both within and outside frameworks), as well as for data storage. That's about it - I've not been looking into the real nitty gritty of xml.

Maybe that is why I was pretty blown away when I saw this example on Wayne Graham's blog. It shows how to use something called entity parameters to reuse portions of a XML file throughout the document (as a response to a question by Ray Camden on the Model-Glue mailing list), and even cooler in my opinion, how to use entity parameters to break up a xml configuration file into several separate files. Extremly sweet.
