But I do not think that is really the goal; very very few people would ever use that type of combination of all possible features on one element. (Note, by the way, that if we disregard the latest discussion on @typeof, and look at the minimalist version of the @property change, that code would remain intact:-)) The question is not aping microdata. It is whether we can get non-sophisticated users use RDFa at least on the Lite level. That is a major difference. To make it clear, I am not convinced of the @typeof changes myself but we have to understand the tradeoffs. In terms of usage pattern, the tradeoff is whether <cite typeof="bibo:Book" property="dc:title">Murder at End House</cite> is really the widespread pattern, which also requires an enclosing @rel in a usual page, like <div about="#me" rel="ex:I_own"> <cite typeof="bibo:Book" property="dc:title">Murder at End House</cite> </div> and whether something like <div about="#me property="ex:I_own" typeof="bibo:Book"> <span property="dc:title">Murder at End House</cite> <span property="dc:publisher">Pinguin Books</cite> </div> would be a more 'friendly' usage. The jury is still out... Maybe Peter Mika (explicitly cc-d) can tell us based on the Yahoo experience...
