But then:
1) It incorrectly allows multiple elements in the document content.
2) It doesn't allow processing-instructions or comments.
3) Given a binding for Type_Element that satisfies the rule, there are
(infinitely?) many supertypes of it (and possibly some subtypes of it) that
also satisfy the rule, and that lead to different types for the validate
