What's the feature?

MathML is a low-level specification for mathematical and scientific content on the Web and beyond. See https://www.w3.org/Math/. AMP should support the mathml specification with an amp-mathml tag.

We use the MathJax library to display math formulas on our website https://www.mathjax.org/

To implement the AMP version of these formulas currently, we need to use an amp-iframe or a dynamic svg. It would be great if AMP supported MathML out of the box.

How would this feature work?

Proposing an amp-mathml tag, takes one parameter - a formula

Quadratic formula:

<amp-mathml formula="\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]" />

What browsers are affected?

This should work in all browsers.
