# MathML has evolved for more than 20 years and computing its status from BCD is
9+

10+

# https://caniuse.com/mathml

# https://developer.mozilla.org/en-US/docs/Web/MathML/Element/math
13+

14+
# Note that there are minor disagreements between sources about initial support
15+
# in different browsers. Where either source claims partial support, the
16+
# versions were increased. Following this method, Firefox was increased due to
17+
# BCD, and Safari due to caniuse.com.
