>From your article:

"Note that XML namespaces are used to provide a namespace for the
metadata vocabulary."

I notice from your example that they are using Qnames for attribute values.

It worries me that yet again a W3C WG is flagrantly ignoring the W3C's
own recommendations - such as the SOAP designers - by seemingly not
actually reading the namespace specification.

"Who cares that section 1 of the namespaces specification says that
XML namespaces only apply to element tags and attribute names; let's
just pick a section we like, and ignore the rest of the specification.
Guess someone else has to sort out the mess[1]" - effbot [2]

>From your article:

"I think we're going to need namespacing to make general-purpose
semantic Web processors work correctly..."

Namespacing is great - there are only two problems:

  1) It is only valid in properly served XHTML (which only 10% of the
web can see [3])
  2) Qnames should not be used as attribute values - this only helps
BREAK semantic Web processors.

What a mess.
