Adapt a SAX2 XMLReader as a SAX1 Parser.
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.
This class wraps a SAX2 XMLReader
 and makes it act as a SAX1 Parser.  The XMLReader
 must support a true value for the
 http://xml.org/sax/features/namespace-prefixes property or parsing will fail
 with a SAXException; if the XMLReader
 supports a false value for the http://xml.org/sax/features/namespaces
 property, that will also be used to improve efficiency.
