I was just thinking about it, and... How can you form a page while "separating data from presentation"? Marking up a piece of data just for presentational purposes (in XML) is the same as using a tag like <sup> in HTML, yet the latter is frowned upon.
Anyway my question is: Can you use PHP in an XML file, or XML in a php file? How exactly would that work out...
Signatures are nothing but incriminating.
