The article doesn't mention extensibility and namespaces in the same breath. In fact the word namespace appears only once in the article and it is when I mention that the XML Infoset has namespace information items.

Partitioning is important if multiple parties will be extending your vocabulary. Just look at RSS for examples of where this partitioning has proved useful.
