It seems to me that in theory and practice the "traditional" attribute that is closely bound to its element is the unprefixed case. The fact that unprefixed attribute names don't pick up the default namespace ensures that this association is kept. <x:foo bar="bogus"/> bar here is in no namespace and so easily bound by the application to behaviour determined by x:foo. It is not in some other random namespace that happens to be the default at this point. Conversely prefixed attribute names are useable (and used) for attributes that derive their primary processing independantly of the element. xml:lang example has already been given, the xlink: attributes are perhaps a better example as are xsl: attributes on literal result elements in an XSLT stylesheet. The processing of xsl:use-attribute-sets="..." is entirely determined by XSLT and can be placed on any element whatsoever. These sorts of attributes naturally live in a namespace and end up with prefixed names in the concrete syntax.
