I think that such a transcoder is very helpful because it works for 
all textual formats and also because it is very efficient.

It works only for XML.  It is not bad, when the MIME header is not available.  
But when it is available, we must rely on the charset parameter.

You are advocating different in-band encoding signatures for different 
formats.  I think that this is a significant burden to users and speficiation
