In that case it is empty but still, it is an object. But I understand
what you mean! "Empty" is just to vague as a word to describe this.
Maybe the english vocabulary needs a new term! :p

One such "empty" object would be an iterator that has nothing to
iterate. There are other examples, but there's no way to test if an
object is empty without a method to determine it because various
objects would have different implementations on how to determine if it
is empty.

How can an object be empty? It's an instance of a class. So it is
something.

You could create an "Empty" interface (or rather,
Emptiable since I
don't think you can use Empty):
interface Emptiable
{
public function isEmpty();
}
Then make your validator accept Emptiable objects along
with strings,
arrays, ints, etc.
Maybe you can come up with a better name than Emptiable :)
Yep you can always extend NotEmpty validator and add
particular cases.
I was just wondering if Zend really needed such a "feature", don't
really think so.
Thanks anyway, ;)
