From what I can tell, Hixie doesn't even believe that the vocabularies in the WHATWG microdata spec will actually be published or consumed by anyone. (If he did then I'd hope that [1] was sufficient documentation of a use case.)

As an aside: if this is really the way it goes, what this means is that microdata becomes a syntax for encoding schema.org vocabularies. Which is fine with me, actually, after all, RDFa is there for other purposes. But that also means that the microdata->RDF mapping can become much simpler...

Of course, since microdata wouldn't be able to support that, we're kind of in a chicken-and-egg situation! :)
