It's only an issue of the presentation system, not, not at all!, of 
In some of the documents quoted there, I find an amount of places where 
MathML-content would need to support language, for example, that a 
content-symbol should support an xml:lang attribute. I really don't 
understand this!

That a presentation template (i.e. a recipe to produce presentation 
from content) bears something such is clear but not the MathML-content 
itself !

Your points are valid and it goas as fine-grained as the classroom or 
Actually, if the rendering engine is used by an autonomous learner 
(e.g. a researcher), there's no reason customization of the notation is 
not offered for him as well.

But where, oh where, in MathML-content or in OpenMath would you like to 
put such choices ??
