No. Adam Donahue is correct on this one. The spec says explicitly,
and then belabors the point with examples; defaults don't apply to
attributes. The only attribute that has a namespace is one that
has a prefix.
Now clearly, an application processing an unprefixed attribute will
know the namespace (if any) of the element to which it's attached,
and may well use that information. For example, in
<html:a href="...">
an HTML processor may (& probably should) choose to process that href
attribute in an HTML-ish way; BUT, the href attribute is not, in the
formal terminology of the spec, in the html or any other namespace. -T.
