 From my point of view, MathML is more in a rendering approach. I'm 
interested in XForms input field for web applications because users 
still need a calculator to set them sometimes !

There is no complex mathematics there and a text expression is all what 
is required. XPath doesn't have an XML notation either... and formulas I 
need require a much simpler syntax.

You are right about the parsing problem and an XML notation would be 
better for sure. Even so, an XML notation could be much more disturbing 
for validation tools.

BTW, do you know any MathML tool able to reduce expressions ?
