+% "translate" should be specified for as many arguments aspossible.
+% Besides the better on-screen display of the contents (a math inset looks
+% better than a formula in ERT), it enables LyX to apply some fixes to LaTeX
+% limitations: For example, footnotes in section headings do not work in
+% LaTeX, but LyX produces preamble code to fix that. Of course this works only
+% for footnote insets and not for footnotes in ERT. Example:
+% \section{title \texorpdfstring{\footnote{foo}}{bar}}
+% is some code that may occur in a .tex file created by LyX. The re-import
+% works only because the first argument of \texorpdfstring is specified as
+% translatable in this file.
