I also like the idea of microdata being purely a set of attributes. Mostly because it keeps the markup more readable IMHO. An element attracts a lot more attention when skimming over markup than an attribute does. Especially if the markup is written for readability like: <foo> <voidelementbar> <baz>text</baz> </foo> And I think it's better that the main document structure is what attracts attention, rather than being distracted by microdata markup. Further, not having to change the element structure of the document in order to add microdata makes it somewhat safer to add since there's much less reason to worry about scripts that expects a certain DOM structure breaking. Neither of the two suggested workarounds are particularly nice: 1. Wrapping a <span> around the <itemref> means that microdata attracts even more attention when writing the markup. 2. Putting the <itemref>s last in an element seems opposite from where you'd intuitively put them. It seems to me more intuitive to put them close to where the item is declared, i.e. the 'itemscope' attribute. / Jonas
