MML Math equations in xml

[Collette Yann]

Hello,

I am currently converting some textual equations under the scilab doc 
into mml.
It works fine but the size of the equation are too small and the 
informal equations are not centered.
I found, using xxe, the the informal equation field has some options:
- align
- contentdepth
- contentwidth
- depth
- fileref
- role
- scale
- scalefit
- valign
- version
- witdth
- xml:id
- xml:lang

I think the scale field and the align field will fit my needs. Do you 
recommend a particular scale for the equations (I think 1.5 will be OK) ?
Except fileref (the name of the mml file), align scale, what are the 
functions of the other fields ?
