Seems the factory should use newobject then. The calling code should not know any of that though, right? The table driving the factory would specify the exe?

OK.

That last would require a subclassed factory that would be able to build a special empty object. A single abstract factory could create a factory object which would build that customized empty object. Right?

Thanks!
