 Very good idea IMHO. This would make it easier to deal with documents 
that use QNames in content. This callback should also be called to 
notify when the default namespace changes.

I'm not sure to understand you ont this. Do you mean that the attribute 
callback could report the value of the attribute by chunks ? Or the name 
of the attribute ?
