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.
