From: dmitry@zend.com (Dmitry Stogov)

I don't understand what are you going to demonstrate with this example.
Did you try to run it?
It produces error as expected.

DOMDocument() in your example is a user-space class that is not related 
to internal ext/dom class. If you like to use internal class that is 
overriden in namespace you can use ::DomDocument instead.

The "use DomDocument as test;" is useless from my point of view.
You always may override internal classes in namespaces.

Thanks. Dmitry.
