Sam, thanks for the fast feedback…

internal tags don’t need the prefix, they need the namespace.

By setting the default namespace locally on the xhtml:body (or xhtml:div if we all change to that), then no extra characters are required.

Thanks for the correction, I overlooked that. For some reason, when I first implemented my RSS 2.0 feed, I assumed that declaring namespaces was a RSS 0.9x or 1.0 thing only, and although I learned otherwise later, somehow didn’t connect this to the <xhtml:body> case.
