This is tricky. Agenda has a notion of time span, "ox-icalendar" hasn't.
So you would have to test if sexp matches for every day between some
arbitrary chosen dates.

"ox-icalendar.el" relies on "icalendar.el" library, bundled with Emacs,
for converting diary entries. Alas, it doesn't handle sexp entries
either.

I use `org-class' for that.
