[XeTeX] \beginR ...\endR

[Michael Gedalin]

Jonathan,
Thanks a lot. I did not realize these are TeX-XeT primitives and tried 
to use them as environment delimiters. Now I defined new commands:

\newcommand{\LL}{\everypar={\setbox0=\lastbox \beginL \box0 }}
\newcommand{\RR}{\everypar={\setbox0=\lastbox \beginR \box0 }}

and use them for switching LTR-RTL. Should I be cautious ?
Michael
