[Zope] ZClass

[Tom Deprez]

Hi,

Just a little question:

Yesterday, I was working with ZClasses. While making one of my own, I saw
that Zope asked for a value to enter per property.

Why does Zope asks for a value to enter for a new property when you're
making a class? I understand that you've to enter a value when you're
making a Class instance? But while defining a class??? Is this meant as a
default value??

This is particulary strange when working with a propery as date. 
What to do, if you don't want to give a default value? Zope always
complains that you have to give a value.

Please, help to clear my mind

Tom.
