  There is far more simple. Redefine the encoding handler for the advertized
encoding declaration and provide the functions generating the bits you want !
   http://xmlsoft.org/html/libxml-encoding.html#xmlNewCharEncodingHandler
   and
   http://xmlsoft.org/html/libxml-encoding.html#xmlRegisterCharEncodingHandler
user provided handler will override the default ones. And you won't have
to make all this mess or change the code.
