I have GNF normalization in mind.  But I am not sure if we should put 
that in the spec.

I don't think so.  Implementations may issue warning messages, but they 
are required to continue.  Thus, the only difference is warning messages.
Different XML parsers already show different warning messages.  What is 
wrong about that?
