XEP 3 supports right-to-left writing mode, and implements
direction change through fo:bidi-override element. It also
implements bidirectionality (though not yet a full Unicode bidi
algorithm). As far as glyph order is concerned, there should be
no problems with right-to-left writing systems.
However, using Arabic-based script systems in XEP (Arabic,
Farsi, Urdu etc) requires additional care. The problem is as follows:
we don't perform ligaturing and/or glyph shaping. Therefore,
all letters should be coded with their exact presentational variants
(isolated/initial/medial/final), and all ligatures should be
explicitly represented by respective Unicode codepoints.
Hope this helps.
