 With \LaTeX{} in DVI mode and \XeLaTeX, box \emph{saving} commands should not be placed on a line of their own with empty lines above and below. For technical reasons this will produce an empty paragraph. Always place them at the beginning or at the end of a paragraph in the input file. Also, box saving commands cannot be placed in the document preamble with \LaTeX{} (DVI) and \XeLaTeX{}.
 
-In a right-to-left typesetting context (RTL), the \verb+<content>+ argument should be enclosed in a pair of \verb+\beginR+ and \verb+\endR+ commands for correctly typesetting RTL text.
