Re: MathML mfenced tag issue with using angle brackets in MathPlayer and MathJax

The problem is that you have incomplete <mrow> tags.  In the MathJax  
example, in your first set of the examples, the first three have an  
extra </mrow> right before the </math> that doesn't have a  
corresponding <mrow> (the fourth works because it doesn't have that  
extra </mrow>.  For the second set of examples, the first three have  
an extra <mrow> with no closing </mrow>, while the last two don't.   
Looks like there are similar issues in the IE file as well.

If you correct the <mrows> all should work.
