* 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 http://xml.org/sax/features/use-attributes2
* feature flag will have the value true.
*
*
* This module, both source code and documentation, is in the
* Public Domain, and comes with NO WARRANTY.
*
*
* XMLReader implementations are not required to support this
* information, and it is not part of core-only SAX2 distributions.
*
* Note that if an attribute was defaulted (!isSpecified())
* it will of necessity also have been declared (isDeclared())
* in the DTD.
* Similarly if an attribute's type is anything except CDATA, then it
* must have been declared.
