This does seem odd....

...though it's OK, at least in theory, to have both OT and AAT technologies in the same font.

What I *think* should work is to specify Renderer=AAT, and NOT specify Script=Syriac (which may override the Renderer option and prompt fontspec to pick ICU, as script tags are OpenType-specific).

Fr. Michael, if that still doesn't work, get back to me and I'll see if I can think what else to try.
