Wolfgang, your solution works for the small caps, even without defining the font feature. I guess it's because \sc is a standard (la)tex style switch like \it.
No, context doesn’t provide latex style switches but you can define them with \definealternativestyle [bfseries] [\bf] \definealternativestyle [itseries] [\it]
Defining (or at least using) the other font feature (c2sc) does not work, and since (to my knowledge) there is no style like \sc for that in tex, we have to define it using the font feature.
In MKII \sc switch to a different font but MKIV can just enable the “smcp” feature. Adding “smcp=yes” doesn’t work as option for \setmainfont because you can use \definfontfeature and overload the “default” set, the only valid options from \definefontfeature are “script”, “expansion” and “protrusion”.
