+ * SAX2 extension to augment the per-attribute information

+ * 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>.

+ * </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.
