Asking for a php countable interface should be sufficient. I think it's safe to
say any container object containig 0 contained objects is empty. No ? php
empty() does that with arrays (but not with countable objects).

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, ;)
