Hmm, not sure if this is a good idea, see below.

Maybe we can have a features=ms_arabic
instead of defaulting to MS' recommendation. So in the final high-end user
interface we can have keys like
featureset=ms_arabic
But I agree with Hans that this is a matter that needs more thought. For
example, Traditional Arabic mixes OpenType and older M$ specs in
Uniscribe, so just plugging in the default features that M$ suggests is
not sufficient for, eg, vowel function in Tr Ar. Also, what about Arabic
fonts on the mac, so they follow the same specs as M$?
We've still got lots to do before settling on a very high-end interface so
there is time to think about this some more...
Best wishes
