/**
 * This interface defines a factory which can be used by documents
 * to provide namespace-aware element creation.
 *
 * <P> A variety of implementation techniques are possible for this
 * interface.  Among them are compiled-in mappings between element
 * names and classes, mappings defined in configuration files, ones
 * derived from the document as it is parsed, and using namespaces
 * to identify packages to be used with classes whose names correspond
 * to elements.
 *
 * <P> DOM implementations will have constraints on the implementation
 * classes returned by this factory, typically that they be subclasses
 * of their implementation base class.
