Namespace Pedantry, Tim Bray. The [Namespaces in XML] Recommendation does not define, in any useful sense, what a namespace is, but that fortunately need not concern us here today and some examples of namespaced and non-namespaced elements and attributes. I don't know if he'd hate that term too but I need to talk about XML elements and attributes that have no namespace for RDF/XML, which Tim also worked on in the original RDF working group.
