 A JAXP Source implementation that supports the parsing fast
 infoset document for use by applications that expect a Source.
 
The derivation of FISource from SAXSource is an implementation
 detail.

 
This implementation is designed for interoperation with JAXP and is not
 not designed with performance in mind. It is recommended that for performant
 interoperation alternative parser specific solutions be used.

 
Applications shall obey the following restrictions:
  

    
The setXMLReader and setInputSource shall not be called.
    
The XMLReader object obtained by the getXMLReader method shall
       be used only for parsing the InputSource object returned by
       the getInputSource method.
    
The InputSource object obtained by the getInputSource method shall
       be used only for being parsed by the XMLReader object returned by
       the getXMLReader method.
