Is the following recurrence specification legal?
 
  DTSTART:20050101T000000Z
  RRULE:FREQ=YEARLY;BYMONTH=3;BYYEARDAY=9;BYWEEKNO=1;BYMONTHDAY=4
 
I assume that if it is it would pick out the following dates within 2005
(leaving aside times for now):
 
  January 1 (week number 1; day pulled from DTSTART)
  January 9 (picked out by BYYEARDAY adjustment)
  March 4 (picked out by combination of BYMONTH and BYMONTHDAY adjustments)
 
Is this correct?

Thank you,
Laird
