I can help you with the XML stuff.

If you XML is valid CI should be able to work with it. What do you mean when you say multiple standards? Are you referring to each XML sources having its own DTD defined? If that is the case, then as long as your XML docs conform to those then CI should be able to handle it.

In short, CI should be able to handle anything you can throw at it. If nothing else you can always extend it your self.
