I merely dropped the namespaces from the examples to
make them simpler and hopefully easier to read.

I wrested with putting namespaces into the examples, but left
them out to make the examples as simple as possible. If I were
to really start implementing this system I would put
the elements into a namespace, and use other namespaces
as appropriate for other elements.

My point in writing the essay was that re-using existing
technologies is a good thing. I tried to show by example
that you can get significant mileage out of XML and HTTP alone.
The idea being that I don't need to wait around for
the Semantic Web to implement the scenarios that Paul Ford
proposed in his essay.
