I agree- which is also why I wouldn't mind adding that itemtype statically in the skin.

I had a conversation with Ian Hickson about the missing multi-itemtype support on Monday. It does not seem to be easy to convince him of the benefits. A set of very concrete and well-presented use cases seems to be about the only thing that might move him to consider it. He also stated that Google et al would adapt their custom indexing to anything we do anyway.

RDFa handles the multiple-itemtype case well, and has the additional advantage of hooking into RDFS et al if needed. Might be something to consider for the parser DOM too, if we can't convince Hixie. The differences in DOM structure between the two are mostly about slightly different names and contents of attributes. Manu Sporny (the W3C RDFa-in-HTML5 WG chair) offered his support as well.
