26//  This class provides an implementation of the XMLTranscoder interface
27//  for a simple 8859-1 transcoder. The parser does some encodings
28//  intrinsically without depending upon external transcoding services.
29//  To make everything more orthagonal, we implement these internal
30//  transcoders using the same transcoder abstraction as the pluggable
31//  transcoding services do.
