--- Comment #5 from Frédéric Wang <[email protected]> ---
So as I see there are several separate issues:

1) Encoding of math formulas
   MathML is the standard used in ODF for encoding mathematical formulas and we
can attach semantics annotation to MathML formulas (e.g. StarMath or LaTeX).
Currently we use MathML with StarMath annotation. Storing images of formula for
ODF document would be a horrible solution IMHO but that can still be used for
exporting to other formats (e.g. HTML).

2) Writing math formulas
   Of course MathML is not intended to be written by hand. Currently we have
StarMath and a visual editor (disabled by default). It would make sense to add
a LaTeX input method.

3) Abstract tree for rendering/navigation of math formulas
   Currently, this tree matches the StarMath syntax which is very poor compared
to MathML or LaTeX. I think we should really have MathML as an internal format
here, so that valid ODF import/export is straighforward and we can manage
additional annotations (LaTeX and StarMath) for more input methods.

IIUC, 3) is the topic discussed here. As Khaled said, using OpenType MATH is
independent of the internal tree.
