"The question is still openness. Could you modify Firefox to gain that capability? Definitely. Could you modify Windows or IE to gain capabilities they don't have? No."

Who cares if you can modify Firefox to add XML capabilities? Can you design an XML application for Firefox users across the globe, counting upon each of them to modify their browsers to run the app? No.

You're still talking about proprietary Microsoft technology, not open. You are talking about a cool feature though, but it is not open. However, I hope you're ready for all your IE users to lower their security settings so they can use that remote XML. If I were using IE, I wouldn't lower my security settings for anyone -- I'd rather not use the site.

BTW, as far as using XML in general, Firefox's user interface and many of its features, and all extensions to it, are open and XML-based. Only the executable and installer are platform-specific.

Anyway, speaking of IE's XML abilities, have you used IE's RSS feeds lately? Didn't think so.
