+% \subsection{Additional note on \texttt{dmg} convention}
+% \label{sec:additional-note-dmg}
+% \NEWfeature{v1.3} According to \textcite[6]{dmg}, Arabic
+% \arb[trans]{'i`rAb} may be rendered into |dmg| in three different
+% ways:
+% \begin{compactenum}[(a)]
+% \item \label{ref:dmg-full-rend}In full:
+%   \NoArbUp\arb[trans]{\cap{`amruNU}}\ArbUpDflt\,;
+% \item \label{ref:dmg-up-rend}As superscript text:
+%   \arb[trans]{\cap{`amruNU}}\,;
+% \item Discarded: \arb[trans]{\cap{`amr}}.
+% \end{compactenum}
+% \DescribeMacro{\arbup} By default, \package{arabluatex} applies rule
+% \ref{ref:dmg-up-rend}. Once delimited by a set of Lua functions,
+% every \arb[trans]{tanwIn} is passed as an argument on to a
+% \cs{arbup} command which is set to \cs{textsuperscript}.
+%
+% \DescribeMacro{\NoArbUp} \DescribeMacro{\ArbUpDflt} \cs{NoArbUp} may
+% be used either in the preamble or at any point of the document in
+% case one wishes to apply rule \ref{ref:dmg-full-rend}. The default
+% rule \ref{ref:dmg-up-rend} can be set back with \cs{ArbUpDflt} at
+% any point of the document.
+%
+% \DescribeMacro{\SetArbUp} Finally, \cs{SetArbUp}\marg{formatting
+% directives} may be used to customize the way \arb[trans]{tanwIn} is
+% displayed. To take one example, here is how Arabic
+% \arb[trans]{'i`rAb} may be rendered as subscript text:---
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluacode}
+\SetArbUp{\textsubscript{#1}}

+^gAmi`aN muhaddamaTaN mi'_danatu-hu.}
+\end{arabluacode}
+% \iffalse
+%</example>
+% \fi
+%
+% As shown in the above example, |#1| is the token that is replaced
+% with the actual \arb[trans]{tanwIn} in the formatting directives of
+% the \cs{SetArbUp} command.
