It should just validate against whatever it knows how to validate against. In the hopefully unlikely event that two different specifications approved by legitimate standards bodies specify conflicting conformance requirements, the validator would have to either choose one, or let the author manually choose. But I don't think we need to worry about that until we come to it. A validator could certainly validate both Microdata and HTML+RDFa.
