/**
 *  A JAXP Result implementation that supports the serialization to fast
 *  infoset documents for use by applications that expect a Result.
 *
 *  The derivation of FIResult from SAXResult 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 serializer specific solutions be used.
 *
 *  General applications shall not call the following methods:
 *   

 *     setHandler
 *     setLexicalHandler
 *     setSystemId
