 * - `Formula`: Async function used for obtaining a computed value such as amount (rate * qty).
 * - `Default`: Regular function used to dynamically set the default value, example new Date().
 * - `Validation`: Async function that throw an error if the value is invalid.
 * - `Required`: Regular function used to decide if a value is mandatory (there are !notnul in the db).
