[Zope] Optional date properties (Zope 1.11)

[Alexander Staubo]

I thought I could add an optional date property to my Z Class' property
sheet, but no -- it seems Zope requires that you fill in a valid date.
Is there a workaround?

Isn't this inconsistent with other properties' behaviour, though?
Wouldn't it be logical that an empty date value as entered in Zope's
management screens would represent "None" or at least a generic "zero"
date?
