I believe you, but I am seeing what I am seeing. Perhaps one problem is 
that everyone shows MathML in fragments. I am sure there is a way to 
screw up the markup in the page info and perhaps that is what I am 
doing. I have taken this file and taken various things out of it. I see 
"x 2" with no superscript. One is supposed to be able to do this, yes?
