      Note 1:  Limit if BYMONTHDAY is present; otherwise, special expand
               for MONTHLY.

      Note 2:  Limit if BYYEARDAY or BYMONTHDAY is present; otherwise,
               special expand for WEEKLY if BYWEEKNO present; otherwise,
               special expand for MONTHLY if BYMONTH present; otherwise,
               special expand for YEARLY.

It should say:

      Note 1:  Limit if BYMONTHDAY is present; otherwise, special expand
               for MONTHLY.

      Note 2:  Limit if BYYEARDAY or BYMONTHDAY is present; otherwise,
               special expand for YEARLY.

Notes:

The change is to "Note 2":
Removed WEEKLY and MONTHLY clause as Note 2 only applies to FREQ = YEARLY.
