//  This class provides an implementation of the XMLTranscoder interface

//  for a simple 8859-1 transcoder. The parser does some encodings

//  intrinsically without depending upon external transcoding services.

//  To make everything more orthagonal, we implement these internal

//  transcoders using the same transcoder abstraction as the pluggable

//  transcoding services do.
