Josh,

You are correct, not only that example but many others too. This is one
of the things that Tantek (and many others) find troubling with RDFa.
I've heard that there's an alternative specification compatible with
XHTML 1.2 coming soon, but going into technical details will only get me
an off-topic email response from Tantek very quickly.
