Why do the subclass implementers need to know the details
of how the smart pointers and reference counting work? It it
because they hold Impl * instead of DOM_* objects, for example, NodeImpl
contains a DocumentImpl *? Could that dependency be removed
if that DocumentImpl * were replaced with a DOM_Document?
