--
-- 'frequency', 'scheduledInstanceRecurrence_frequency' - The frequency (@Daily@, @Weekly@, or @Monthly@).

-- 'occurrenceDaySet', 'scheduledInstanceRecurrence_occurrenceDaySet' - The days. For a monthly schedule, this is one or more days of the month
-- (1-31). For a weekly schedule, this is one or more days of the week
-- (1-7, where 1 is Sunday).
--
-- 'occurrenceRelativeToEnd', 'scheduledInstanceRecurrence_occurrenceRelativeToEnd' - Indicates whether the occurrence is relative to the end of the specified
-- week or month.
--
-- 'occurrenceUnit', 'scheduledInstanceRecurrence_occurrenceUnit' - The unit for @occurrenceDaySet@ (@DayOfWeek@ or @DayOfMonth@).
