Partition nodes without a compatible have no restrictions on additional properties. Fix this by ensuring 'unevaluatedProperties' is set when there's no compatible property. If there is a compatible property, then there should be a specific schema for it which will enforce 'unevaluatedProperties'.

pre-programmed by the factory. Some flashes might provide both.
