For a longer exposition, see Mark Birbeck’s post at http://internet-apps.blogspot.com/2007/07/rdfa-used-in-joost.html.

In case you successfully pass the validation, you’ll be rewarded with an icon stating that you have produced valid XHTML + RDFa.
You can then choose between two versions:

PS: In case you need some material to play around, have a look at the RDFa Test Case repository.
