A possible solution for MATHML representation

Hi everybody.
I'm an individual and I recently created a W3C account to post a related
XForms project.
https://www.w3.org/community/blog/2023/03/07/proposed-group-declarative-dynamic-extensions-to-html-community-group/

This is a set of html extensions that aims to reduce javascript requirement
and perform a lot of dynamic behaviours in a declarative way.

There is a feature you might like. This project aims to extend the html
separation of concerns by adding a layer between styles and the html page
itself feeding the shadow dom inner content of xml / html elements. When I
imagined it, I was discreetly thinking about a possible way to resolve the
lack of rules, for the user agent, to represent MATHML elements.
Then, you may or may not be interested in this project to find a solution
to this point.

For now I'm totally alone on this project, and I will greatly appreciate
feedback.

Finally, I will be happy if there are some supporters to this newly
proposed community group.
Thank you,
Flavien.
