MathML in HTML5: Internet Explorer 9 is Broken
I have some good news and some bad news. First, the good news is that the new HTML5 standards initiative includes support for MathML and has been embraced by all browser vendors. This should reduce the barriers to producing web content with accessible, searchable, and interoperable mathematics.
Now the bad news. Unfortunately, MathML support in the next version of Internet Explorer 9 appears to be broken, based on our testing of Microsoft's latest Platform Preview. Read the whole story in MathML in HTML5: Internet Explorer 9 is Broken. It only requires a small fix but Microsoft likely will not give it much priority unless the STEM, Education, and Accessibility communities make it clear how important MathML support is for them. Our hope is that you will help us spread the word about this problem and make Microsoft understand the need to make MathML work once again. If you agree, let them know by any and all means at your disposal.
