An interesting thing about XML namespaces is that they are basically a way to autonomously create globally unique names that are still human-readable and writable. (As opposed to GUIDs, for example.) Like `foo:bar`, where `foo` is a local alias for a long and unique string, often an URN. (Of course, this wasn't an original idea of XML.)
