I can technically restrict the implementation to only support the plain 
<math>...</math>, while authors will effectively use <math 
xmlns="...">...</math> for IE+MathPlayer. (That is, Mozilla wouldn't 
actually require the xmlns attribute for the MathML rendering to kick 
in. Authors only put the attribute there for interoperability.) The 
issues now become:
- can  IE+MathPlayer be made to at least support <math 
xmlns="...">...</math>? (from David's recent post, it seems possible in 
- what is the implication for HTML5? Just one of those random attributes 
that people put in their HTML document? (which wll be fine with me, BTW).
- what about generators that emit prefixed tags?
