New attributes for MathML 3.0

Hi,

I have an implementation of MathML 2.0 to display mathematical information
on web www.fmath.info.

And I suggest some modifications for MathML 3.0:

1. Why Radicals <msqrt>, <mroot> don't have *linethickness* attribute like *
mfrac* ?
  I think must be inserted. In my implementation I have added:

2. Add to *Mathematics style attributes common to presentation elements:*

   - attribute *border -* to have a border around a box Ex: <mrow
   border='1'>

http://www.fmath.info/formula/ex/mi.jsp#main


   - attribute *bordercolor* - the color of border


What do you think?

I am new to participate to a specification and I don't know what are the
next steps to have in the new spec my ideas.

Thank you and I hope I could help
