This Is great I have been having problems all weekend with this RDFa+RSS
[1], I have got as far as transforming to RSS using the distiller [2],
but my tests have produced some wild results, which I have put down to
the markup in my test (and me just getting to grips with RDFa), anyway
after looking at your examples, your markup contains minimal html and
only block elements, this probably confirms my suspicions :)

Inspiring work Simone thanks.
