/**
* Defines the API that wraps an {@link org.xml.sax.XMLReader}
* implementation class. In JAXP 1.0, this class wrapped the
* {@link org.xml.sax.Parser} interface, however this interface was
* replaced by the {@link org.xml.sax.XMLReader}. 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
* {@link javax.xml.parsers.SAXParserFactory#newSAXParser()} 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 <code>&quot;javax.xml.parsers.SAXParserFactory&quot;</code>.
* 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 {@link org.xml.sax.HandlerBase} or the
* {@link org.xml.sax.helpers.DefaultHandler} are called.<p>
*
* Implementors of this class which wrap an underlying implementation
* can consider using the {@link org.xml.sax.helpers.ParserAdapter}
* class to initially adapt their SAX1 implementation to work under
* this revised class.
