It's not using a standard interface.  It goes straight to the 
implementation, here's how it's done:
     class JDK15XML1_0Parser extends SAXParser {

         JDK15XML1_0Parser() throws org.xml.sax.SAXException {

             super(new DTDConfiguration());
             // workaround for Java 1.5 beta 2 bugs
com.sun.org.apache.xerces.internal.util.SecurityManager manager =
                     new 
com.sun.org.apache.xerces.internal.util.SecurityManager();
             setProperty(Constants.XERCES_PROPERTY_PREFIX + 
Constants.SECURITY_MANAGER_PROPERTY, manager);

         }
     }

where:
SAXParser is com.sun.org.apache.xerces.internal.parsers.SAXParser
DTDConfiguration is 
com.sun.org.apache.xerces.internal.parsers.DTDConfiguration

And of course, if Xerces jars are on the classpath, these would be:
org.apache.xerces.parsers.SAXParser and 
org.apache.xerces.parsers.DTDConfiguration.

It looks up Xerces, then JDK, if failed, it actually falls back to the 
SAX interface, that is XMLReaderFactory.
