-/**
- * This class extends the SAX2 base handler class to support the
- * SAX2 {@link LexicalHandler}, {@link DeclHandler}, and
- * {@link EntityResolver2} extensions. Except for overriding the
- * original SAX1 {@link DefaultHandler#resolveEntity resolveEntity()}
- * method the added handler methods just return. Subclassers may
- * override everything on a method-by-method basis.
- *

- * <em>This module, both source code and documentation, is in the
- * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
- * </blockquote>
- *
- * <p> <em>Note:</em> this class might yet learn that the
- * <em>ContentHandler.setDocumentLocator()</em> call might be passed a
- * {@link Locator2} object, and that the
- * <em>ContentHandler.startElement()</em> call might be passed a
- * {@link Attributes2} object.
