John, I imagine we'd be happy to help you with this. Feel free to contact
me directly off-list, and we can work out any details.

InDesign 1.0 offers full support for the OpenType 'liga' feature, which is
to say it automatically uses any and all arbitrary, non-contextual
ligatures which are intended to be on by default--though you can turn them
off if you wish.

InDesign 1.0 does not support 'dlig' (discretionary ligatures) or 'clig'
(contextual ligatures). Note that contextual means a context outside of the
characters being turned into a ligature. 'liga' alone is sufficient to
handle multi-character ligatures from arbitrary numbers of characters.
(There may be a limit, but I don't know offhand.)

I have an Arabic OpenType font that has over 260 of the Arabic ligatures in
it. However, the selection of the ligatures is done through the LIGA feature
and does not need a control character.
