How to share multiple dates for one specimen?

[GoogleCodeExporter]

Some specimens have multiple dates on their specimen label, for example: one 
for the flowers and one for the plant itself: "May 16 and August 7, 1991". For 
insect specimens I've even seen triple dates.

How do we advise to express such a date in eventDate 
(http://rs.tdwg.org/dwc/terms/index.htm#eventDate)?

1) No eventDate
verbatimEventDate: May 16 and August 7, 1991
eventDate: 
startDayOfYear: 
endDayOfYear:
year: 1991
month: 
day: 

2) Separated dates in eventDate:
verbatimEventDate: May 16 and August 7, 1991
eventDate: 1991-05-16|1991-08-07
startDayOfYear: 
endDayOfYear:
year: 1991
month: 
day:

After talking with John, I've decided to recommend option 1: no eventDate. 
Option 2 is not ISO 8601 compliant. For an example see:
