Your suggestion is as follows:

This does not break existing implementations, because it allows 
implementations to choose XML 1.0 name characters or XML 1.1 name 
characters.  However, this optionality hampers interoperability.  
As far as I see it, we have seen that some options of XML (e.g., optional 
fetching external DTD subsets) have caused enough interoperability 
problems.
