\title{Editing right-to-left text with left-to-right notes}

\maketitle
\begin{abstract}


In this file, we provide an example of an edition with right-to-left text and left-to-right notes, using \XeLaTeX.

\begin{itemize}
	\item The `hebrew' environment allows us to write Hebrew right-to-left.
	\item The \verb+\Xbeforeinserting{\LTR}+ makes the critical notes to be typeset left-to-right.
	\item The \verb+\Xwraplemma{\RL}+ assures the lemmas, which are in Hebrew, be typeset right-to-left.
	\item The \verb+\Xwrapcontent{\textenglish}+ assures the content of the note is marked as English text. 
	\item As the `Ezra SIL' font transforms a `]' to a `[', we use a `[' as lemma separator, that will be typeset as `]' by `Ezra SIL'. So the need for \verb+\Xlemmaseparator+ is not directly linked to reledmac.
\end{itemize}
