It isn't microdata or RDFa that are in scope for HTML, it's the use cases 
that they solve. I agree that there are use cases that both RDFa and 
microdata address that are in scope for HTML, so insofar as that goes, 
RDFa and microdata are both in scope for HTML. It's just that RDFa, as 
designed, has problems that IMHO must be resolved before it would be 
appropriate for HTML; microdata is basically RDFa with those problems 
resolved. (Naturally, in designing microdata, other design features that 
may have been the result of requirements for RDFa were not addressed; for 
example, microdata doesn't support giving types to values. I designed 
microdata based on the use cases that were provided, and nothing else.)

Which use cases does microdata not address? (There are lots of use cases 
that were put forward as reasons for RDFa that RDFa doesn't address, e.g. 
it doesn't hook into the drag-and-drop model to support dragging contact 
information from an (X)HTML page to an OS address book program.)
