I would strongly suggest that everyone back out to RSS 0.9x until the
namespace situation and how various technologies can relate to it is
resolved.

Then I would strongly suggest a set of example RSS 2.0 feeds, with
namespaces, be placed into a directory for testing. Many folks may
need to update their tools to process namespace, such as compiling in
namespace support with PHP and so on.

Namespaces are a major tech change, and as such, needs a roll out
plan, plenty of advance warning, and careful documentation (about
concept AND about impact to popular technology).
