But all the RTL work is done by the ICU, afaik, anyway, not that
important. You clearly meant xetex, not pdfetex.

sorry, I see that now (but in my defense, it seems to do a bit of
aat as well).

\def\leftline#1{\hbox dir TLT to \hsize{#1\hss}}
\def\rightline#1{\hbox dir TLT to \hsize{\hss#1}}

First, somebody has to come up with a 100% correct definition of
"correct format". For example, is "3.5" section five in chapter three,
or section three in chapter five?

Second, this should be coded in a lua node processing step or as an
otp (these still work).

Best wishes,
