"The "additionalProperties" keyword can't see into the example.com/schemas/sharedproperties schema, so it doesn't matter what it contains."

Is this required behavior in classic JSON Schema, or just the result of poor execution? In other words, could the problem be fixed with conformance requirements without any change to schema syntax?
