The unofficial guide to migrating Google Rich Snippets to schema.org

"If you’ve been using microformats or RDFa to mark up your Google Rich Snippets, sorry, you backed the wrong horse."<p>I think that's supposed to be a joke, but it just comes off as insulting instead.

Can you use this microdata with your own CSS/HTML markup or you can't include your own classes ? i.e. your formats must look identical to these ?
