Examples of org.xml.sax.ext.Attributes2

org.xml.sax.ext.Attributes2
rg/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.
