Properties
| Property | Type | Description |

appearance? | | string | { down?: string; normal?: string; rollover?: string; } | Custom appearance stream for the checkbox. Can be a raw PDF content stream string (used for all states), or an object with optional normal (/N), down (/D), and rollover (/R) appearance strings.
