I agree with your analysis. However, in an XML 1.1 document, whether you
have <example xmlns='' /> or <x:example xmlns:x='' /> does not matter,
in both cases you have the "example" element in no namespace, and I'd
expect the same from the @namespace rules. I think if either of these is
an error, both should be an error.
