Also with the current state of play the MathML may be hidden in various ways while still being available to screen readers. wikipedia for example serves its mathematics (by default) as svg or png but with MathML hidden in a form that should be usable by screen readers and other assistive technology, see https://en.wikipedia.org/wiki/Help:Displaying_a_formula#Native_MathML The details depend on your browser and settings but for example if I view the source of https://en.wikipedia.org/wiki/Integration_by_parts I see all the mathml hidden via style="display: none;" as for example <span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle \int _{\Omega }\nabla u\cdot \nabla v\,d\Omega =\int _{\Gamma }u\,\nabla v\cdot {\hat {\nu }}\,d\Gamma -\int _{\Omega }u\,\nabla ^{2}v\,d\Omega ,}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <msub> <mo>∫<!-- ∫ --></mo> .........
