/**
* Defines the API that wraps an <code>org.xml.sax.XMLReader</code>
* implementation class. In JAXP 1.0, this class wrapped the <code>
* org.xml.sax.Parser</code> interface, however this interface was
* replaced by the <code>XMLReader</code>. For ease
* of transition, this class continues to support the same name
* and interface as well as supporting new methods.
*
* An instance of this class can be obtained from the
* <code>SAXParserFactory.newSAXParser</code> method. Once an instance
* of this class is obtained, XML can be parsed from a variety of
* input sources. These input sources are InputStreams, Files, URLs,
* and SAX InputSources.<p>
* This static method creates a new factory instance based
* on a system property setting or uses the platform default
* if no property has been defined.<p>
*
* The system property that controls which Factory implementation
* to create is named "javax.xml.parsers.SAXParserFactory".
* This property names a class that is a concrete subclass of this
* abstract class. If no property is defined, a platform default
* will be used.</p>
*
* As the content is parsed by the underlying parser, methods of the
* given <code>HandlerBase</code> or the <code>DefaultHandler</code> are
* called.<p>
*
* Implementors of this class which wrap an underlaying implementation
* can consider using the <code>org.xml.sax.helpers.ParserAdapter</code>
* class to initially adapt their SAX1 impelemntation to work under
* this revised class.
