I'm guessing, since I don't have the fonts handy, that they have AAT 
tables (see previous message), since they ship bundled with Mac OS.

AAT is a clever technology, but since it is Mac-only and not supported, 
even on the Mac, by major developers like Adobe, it is something of a 
dead-end, and unless one is making a font for Apple there is very little 
incentive to do the considerable work necessary to develop AAT tables. 
Also, because the functionality of AAT and OT are not perfectly 
parallel, there is no easy path to convert layout intelligence from one 
to the other. I know almost no font developers who are making AAT fonts, 
whereas almost everyone is making OT now.
