[development] Skipping validation on date field

Yes, I'm using a date element.

I'm doing what you describe in your second option below. When the user doesn't select anything, the date array passed has empty values (in essence is the same as "mushing them into nothing"), and I suspect that is why it doesn't pass validation... because an empty value is not a valid date.

So I assume I need a way to say that no date selected is considered valid.

(And doesn't the date module provide this?)  If not, and you want to roll your own, form_example_elements.inc in the Examples Form Example shows how to do it. You could then use a '#validate' function to short-circuit validation...
