RE:  Attributes with default namespaces? XSLT Rec   que
Hi Ken,

I would rather say the notion of 'being in no namespace' slipped my attention.
I found the relevant part in section 6.2:

        "A default namespace declaration applies to all unprefixed element
         names within its scope. Default namespace declarations do not apply
         directly to attribute names; the interpretation of unprefixed
attributes
         is determined by the element on which they appear.

        ...The namespace name for an unprefixed attribute name always has no
value...."

        (http://www.w3.org/TR/2006/REC-xml-names11-20060816/#defaulting)

Thanks for sharpening my attention..

Kind regards,
Geert
