  To me a plain well-formedness error clearly take precedence over a
namespace error since document which doesn't conform to REC-xml-names can
still be usable data, while a not well-formed one must break. 
  I still think the error is miscategorized, and will supress it from 
my regression runs. And I really don't think XML parsers should report
a namespace error there but the XML-1.0 wellformedness error which is
far more critical and general.
