Hi, Hans:
no, in such cases, just create another typeface with relevant fonts using smallcaps and then switch to that typeface
OK. I see. Thanks.
hm, it's nbot that complex, just define a featureset and use it; one can even adapt features in between if needed (dynamic features)
How to use dynamic features? it is not documented in co-typography and co-fonts. is there such interface like: \definefeature[onum][onum=yes] \definefeature[smcp][smcp=yes] {\rm\bf\onum\smcp Hello 2008!}
you can be pretty sure that whatever you 'predefine' (font-blabla-using-oldstyle-and-smallcaps) will have exceptions and then we end up with n! possible combinations
not n!, but 2^n. last question: is it possible to add fontconfig-like interface? if I define to use minion famaily, then all the alternatives are automatically defined like xetex? Yue Wang
