Using only RDATE means loosing data (namely the actual intent) and the=20
possibility to edit the data later on.=20
If you have a course with the following data (from a student's perspecitive=
):
Mar 2, 7, 9, 14, ...
Can you be sure that it is really meant as a course that happens every mond=
ay=20
and wednesday? No, you'll have to look at your calendar for every date. If=
=20
you see that the recurrence is every monday and friday, you don't need to=20
look at your calendar, but sooner or later you'll remember.

Also, in KOrganizer we also use iCalendar to store the whole calendar on di=
sk,=20
and there we absolutely need a way to store the way in which a date is=20
recurring. Simply discarding all RRULES and using RDATES instead might be a=
=20
solution for sending invitations, but it's not a solution for storing on=20
disk, and also not for exchanging events between two calendaring applicatio=
ns=20
(i.e. import/export of events).=20

Cheers,
Reinhold
