Peter, actually I suspect Philippe is thinking that in the case of RTL, the *glyphs* are placed in reverse order and then he is asking how can the ligation take place.
While I don't know much about RTL scripts, if the logic order is ALEF + LAMED, but the presentation order is LAMED + ALEF *because of the RTL nature* do you write the rule as ALEF + LAMED = ALEF_LAMED_LIGATURE or LAMED + ALEF = ALEF_LAMED_LIGATURE ?
