Default. Not much of a risk of emitting triples by accident.

It was suggested in the reference Tony sent, which was really more about N3. Again, the odds of a script tag with both a matching @type and @id seems pretty negligible. Plus, the parser emits statements. A graph context is dropped if their added to a container that doesn't support contexts.
