Sorry to have used the wrong name, the correct name is "parallel 

MathML has this ability to have a presentation markup hinting to a 
It is called "parallel markup" and I think it's very important for any 
purpose like "copy and paste", "machine-readability", or just about any 
semantic web application.

Mathematics were relatively ready for such purposes... merging them 
into CSS would sort of loose this!


PS: it would even loose the ability to consider as math an XML-extract 
whereas previously it was possible to have, with limited generality, a 
good consideration of the mathematical nature of a 
presentation-mathml-snippet, allowing it to be pasted in Maple and 
Mathematica, for example.
