/**
 * <p>
 * This is a very simple XML EntityResolver.  If
 * you are parsing an XML document using a DocumentBuilder,
 * and you set the DocumentBuilder's EntityResolver to an
 * instance of this class, then we never attempt to resolve
 * XML documents on the Internet.  Instead we use a local
 * copy of the DTD.
 * </p>
 *
 * <p>
 * This is done so that the XMLReportTest.java JUnit test will
 * not fail when the test is run on a non-networked machine,
 * or when webpages must be accessed through a proxy server.
