This interface
defines an extension to the core Locator
interface. If the implementation supports it, then the
Locator object passed to
ContentHandler.setDocumentLocator( ) will
implement this interface. You can also test for support by querying
the feature named
"http://xml.org/sax/features/use-locator2".
