| Elements of a disjunction may be marked as preferred. |
| If there is only one mark, or the users constraints a field enough such that |
| only one mark remains, that value is the default value. |
| |
| In the example, `replicas` defaults to `1`. |
| In the case of `protocol`, however, there are multiple definitions with |
| different, mutually incompatible defaults. |
| In that case, both `"tcp"` and `"udp"` are preferred and one must explicitly |
| specify either `"tcp"` or `"udp"` as if no marks were given. |
