RRules in Recurrence

In the schema we used to develop the PIM, there are 1-infinite rrules in a Recurrence.

Is this correct?

As I understand the logic:

A Recurrence is a means to compute a collection of dtStarts.
1.
It begins with a single dtStart.
2.
It adds 0-to-many rDates
3.
It computes additiona rDates with RRules
4.
It uses exDate to remove dates from the collection assembled as above.

It is unclear why 0 [no] rrules is not legal.
I think because of the “bag of properties] aspect of the original that this is not clear.
