Sorry for being so slow.  I understand the problem now.

I think the prefix is the problem, as David was trying to get at.  In
IE, you stupidly have to do your CSS rule as

  m\:math  {color: red}

which is not going to be a solution for Mozilla.  The backslash is
important, and as far as I can tell, documented nowhere.

That's a drag.

I think we ran into some problem with this -- I believe 
non-standard CSS properties didn't show up in IE's runtime CSS object
or something like that.  In any event, you are correct that MathPlayer
doesn't read MathML 1 attributes from CSS.

Ugh.  I think you could define rules for m\:math and math, which would
at least avoid having to set a class attribute on every instance.  But
I don't see any way around the double definition.  

It is surely unfortunate that the weaknesses in the IE+MathPlayer and
Mozilla implementations are so complementary.  Sigh.
