Description

[Emilio Cobos Álvarez (:emilio)]

Fred, who works at Igalia and implemented MathML in WebKit, pointed out we could try to simplify some stuff.

For stuff that we could / should consider removing.

Some of it is really invasive (the script size multipliers come to mind), so it'd really be nice to simplify some of this stuff.

As announced on mozilla.dev.platform, a MathML Refresh CG has been launched early this year and some simplification is being discussed and formally approved:

Let's use this as a meta bug similar to WebKit's one ( https://bugs.webkit.org/show_bug.cgi?id=195797 )

This is bug 1587577

https://lists.w3.org/Archives/Public/www-math/2016Aug/0008.html

This is bug 1548524, bug 1573438 and bug 1575870 basically.

Most mstyle attributes have been removed for a long time. The remaining ones are bug 1548471. Also we might want to map mathvariant/displaystyle/scriptlevel to the CSS properties described in the spec, instead of internal ones.

Also the appendix on http://www.mathml-association.org/MathMLinHTML5/A1.html

That doc is obsolete, current suggestions/discussions are in the MathML Refresh CG's issue tracker: https://github.com/mathml-refresh/mathml/issues
