Defines the API that wraps an XMLReader implementation class. In JAXP 1.0, this class wrapped the Parser interface, however this interface was replaced by the 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 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.
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.

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.
 As the content is parsed by the underlying parser, methods of the given HandlerBase or the DefaultHandler are called. Implementors of this class which wrap an underlying implementation can consider using the ParserAdapter class to initially adapt their SAX1 implementation to work under this revised class.

    Sets the particular property in the underlying implementation of XMLReader. A list of the core features and properties can be found at 
http://sax.sourceforge.net/?selected=get-set.
 All implementations that implement JAXP 1.5 or newer are required to support the XMLConstants.ACCESS_EXTERNAL_DTD and XMLConstants.ACCESS_EXTERNAL_SCHEMA properties. 

  
      Setting the XMLConstants.ACCESS_EXTERNAL_DTD property restricts the access to external DTDs, external Entity References to the protocols specified by the property. If access is denied during parsing due to the restriction of this property, SAXException will be thrown by the parse methods defined by SAXParser. 
      Setting the XMLConstants.ACCESS_EXTERNAL_SCHEMA property restricts the access to external Schema set by the schemaLocation attribute to the protocols specified by the property. If access is denied during parsing due to the restriction of this property, SAXException will be thrown by the parse methods defined by the SAXParser. 
  

Params: name – The name of the property to be set.
value – The value of the property to be set.
Throws: SAXNotRecognizedException – When the underlying XMLReader does
  not recognize the property name.
SAXNotSupportedException – When the underlying XMLReader
 recognizes the property name but doesn't support the property.
