Xerces does this? Are you sure? Which version? Is this through the 
SAX API or something else. I could swear I just tested this yesterday 
in a different (still SAx context) and Xerces was not reporting it 
while Crimson was.

I don't think XOM does that. If it does, it's a bug. XOM is very 
careful about where and when the xml prefix is mapped. If you can 
reproduce a case in which XOM ignores the namespace URI for the xml 
prefix let me know so I can fix it. Or maybe you just meant XOM won't 
add a namespace declaration for the xml prefix? That's true. However, 
if you try to use the wrong URI or the wrong prefix, XOM should toss 
an exception.
