Since XML-Data was never a work item for a W3C working group, there is
no one who can official declare its passing, but yes, it's dead.
I still haven't had time to give XSchema a proper going-over, but from
what I've seen, XSchema and DCD are not competing for the same
- XSchema defines an instance-based representation of DTDs
- DCD defines an alternative to DTDs
Does this make sense?
