attribute "data-variant" after update of m2svg

[lnatal2]

This test file contains part of the html output file and svgs images of the book Principia Mathematica Vol.1. It validates with NU checker but not ebookmaker. m2svg was updated in order to allow the use of some unicodes in this particular book. Running ebookmaker, got a lot of attribute "data-variant" not allowed here, mostly for grouped equations but for simple inlines as well. Inlining some of the svg images didn't cleared the errors reported. Thanks!

By testing in another file, I don't get any error concerning "attribute "data-variant" not allowed here". It may be due to the fact that in the above example there are unicodes (1 or more than 1) enclosed in inline markups and in grouped equations as well.. So this error is not related to the update in m2svg as I thought initially.

in my testing, it was only the epub2 validation that choked on the data-variant attribute. Making a script to remove that attribute was easy enough for Gemini to produse working code. (attached)

It works now, ebookmaker just validated Principia01, many thanks!
