Usages we don't want don't have to be permitted just because the
schema makes them feasible.  These can be forbidden at some other
layer.  Though I agree that it's better to formally express (e.g., via
schema) just the rules we want; I don't expect perfection.

Yes, and Jim's design meets those requirements.
