* SAX2 extension to augment the per-attribute information

* and the http://xml.org/sax/features/use-attributes2

* 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.
