/**
 * SAX2 extension to augment the per-attribute information
 * provided though {@link Attributes}.
 * If an implementation supports this extension, the attributes
 * provided in {@link org.xml.sax.ContentHandler#startElement
 * ContentHandler.startElement() } will implement this interface,
 * and the <em>http://xml.org/sax/features/use-attributes2</em>
 * feature flag will have the value <em>true</em>.

 * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
 * </blockquote>
 *
 * <p> XMLReader implementations are not required to support this
 * information, and it is not part of core-only SAX2 distributions.</p>
 *
 * <p>Note that if an attribute was defaulted (<em>!isSpecified()</em>)
 * it will of necessity also have been declared (<em>isDeclared()</em>)
 * in the DTD.
 * Similarly if an attribute's type is anything except CDATA, then it
 * must have been declared.
