Content Negotiation

If I remember correctly, you need to serve MathML documents with the XML mime type in order for Mozilla based broswers to kick in. This would be very useful for those of us wanting to include complex math in our blogs. However, I’m well aware of the issue of a non-well-formed page being served as XML. It breaks the entire page. (Jacques Distler has written in grea detail about everything necessary to bulletproof MT, including trackbacks and such.) As such, this should be an option and further more, disabled by default with a big warning next to it.
