+%
+% \subsection{Hooks into \pkg{fontspec}}
+%
+% Historically, \cs{mathrm} and so on were completely overwritten by \pkg{unicode-math}, and \pkg{fontspec}'s methods for setting these fonts in the classical manner were bypassed.
+%
+% While we could now re-activate the way that \pkg{fontspec} does the following, because we can now change maths fonts whenever it's better to define new commands in \pkg{unicode-math} to define the \cs{mathXYZ} fonts.
