In XHTML you can avoid using xml:base (by not specifying a base) and  
xml:id (by using id). You can't avoid xmlns. That's why I think xmlns  
comes before these two in order of importance.

It is also very difficult to avoid xml:lang which, just like "/>",  
can be scattered all over the file. That's why I'm trying to see if  
there is a possibility of a conformant solution. There's at least a  
practical solution that will work, which is to use the lang attribute  
alone, although this isn't conformant with XHTML.
