As long as human beings are the only plausible "end consumers" of these
documents, their semantics will always be determined ultimately by fuzzy
things like intentions and expectations. The semantic constraints I am
talking about are one step away from these "ultimate" semantics; they
tell you that an integer contained in a given element cannot be greater
than 100, but they don't tell you why. These are still semantics to me
and they provide tremendous value when you want to process a broad range
of documents generically (which might, for example, involve generating
an application-specific interface for any arbitrary schema).
