| * Book new cargo |
| * |
| * An example of UI validation: |
| * - you can't choose equal locations |
| * - earliest deadline you can choose from the date picker is tomorrow (we could set any date that the domain wants). |
| * |
| * More elaborate validation rules could be enforced in a real domain to avoid even touching |
| * the backend with invalid data (of course we would still need backend validation). |
