+  With \luatex{} there is another approach to make text
+  transformations, with the function |fonts.handlers.otf.addfeature|,
+  which adds new features to an OTF font (substitution and
+  positioning). These features can be made language-dependent, and
+  \babel{} by default recognizes this setting if the font has been
+  declared with |\babelfont|. The \textit{transforms} mechanism
+  supplements rather than replaces OTF features.

+  With \xetex{}, where \textit{transforms} are not available, there is
+  still another approach, with font mappings, mainly meant to perform
+  encoding conversions and transliterations. Mappings, however, are
