<!-- Note: mpadded attributes are not tested since MathML3 did not allow to
set them from mstyle. Also, it is not clear whether munderover's
accent/accentunder could be applied from mstyle, given that the former
clashes with mo@accent. Other legacy mstyle attributes not in MathML
Core or without visual effect are not tested.
