[pmwiki-users] Validate fox form with empty fields

I want to validate the users input in some of the fields of a fox form, but 
it should also be possible to leave these fields empty. I tried using a regex
that matched an empty value, but that didn't seem to work.
I'm not very experienced with either fox or web-forms in general, so maybe
I'm missing something really simple here...
