[XeTeX] \botmark and \firstmark not working for me ...

[John Was]

If you have got to a point where everything works except that the right-hand 
side has slipped to a measurable extent (viz. the height plus depth of the 
left-hand side), then you could measure the left-hand side as an initial 
operation, store that measurement, and start the right-hand side with 
\vskip -\themeasuredamount before setting the Hebrew.

Of course these things tend to get ever more complex (and then someone comes 
along with a neat solution), but TeX isn't particularly slowed up (usually) 
by making rather difficult calculations even if they are frequent, and all 
the nitty-gritty would be packed away in a macro.
