It could be that seeing an XML tag was found to cause brain damage in Microsoft users, I'm not sure.

The Input Panel generates MathML markup for your formulas, but it won't give it to the user. Marko Panic, the program manager for the development of this tool confirmed to me that this was a design decision as they didn't want the end user to be faced with raw XML. The Math Input Panel doesn't offer fallback text representations of the XML markup on the clipboard. The answer below was written under the assumption that you could get MathML markup from Math Input Panel.
