[development] Skipping validation on date field

[Randy Fay]

Without completely understanding what you're up to:

1. I think you should be using a date *element* to do this if you're not
already, so you validate the element as you would expect. But you probably
already knew that. (And doesn't the date module provide this?)  If not, and
you want to roll your own, form_example_elements.inc
<http://api.drupal.org/api/examples/form_example--form_example_elements.inc/6/source>in
the Examples Form Example shows how to do it. You could then use a
'#validate' function to short-circuit validation...

2. If you're already using a date element to do this, you probably need to
make a #validate that mushes the values into nothing when they haven't
selected anything. I suspect that you're currently getting a value that
doesn't equate to empty after you've changed those form elements.

Sorry if I've missed the point, but one of those two ought to help.
