All Implemented Interfaces:

public class StandardElementFactoryRegistry

extends Object

implements ElementFactoryRegistry

1. namespace
2. tag name

and registers a factory class for constructing Object instances associated with an Element hierarchy. This enables an XML document to be extended with new implementations of known interfaces.
