 You may encounter some named types which are used for simplicity.
 
 - `Translation`: a translated property
-    - used for properties: `ask`, `help` and `Pattern.error`
-    - a `dict` with locales as keys and translations as values:
-        ```toml
-        ask.en = "The text in english"
-        ask.fr = "Le texte en français"
-        ```
-        It is not currently possible for translators to translate those string in weblate.
-    - a single `str` for a single english default string
-        ```toml
-        help = "The text in english"
-        ```

 - `JSExpression`: a `str` JS expression to be evaluated to `true` or `false`:
-    - used for properties: `visible` and `enabled`
-    - operators availables: `==`, `!=`, `>`, `>=`, `<`, `<=`, `!`, `&&`, `||`, `+`, `-`, `*`, `/`, `%` and `match()`

 - `Binding`: bind a value to a file/property/variable/getter/setter/validator
-    - save the value in `settings.yaml` when not defined
-    - nothing at all with `"null"`
-    - a custom getter/setter/validator with `"null"` + a function starting with `get__`, `set__`, `validate__` in `scripts/config`
-    - a variable/property in a file with `:__FINALPATH__/my_file.php`
-    - a whole file with `__FINALPATH__/my_file.php`

 - `Pattern`: a `dict` with a regex to match the value against and an error message
-    ```toml
-    pattern.regexp = '^[A-F]\d\d$'
-    pattern.error = "Provide a room number such as F12: one uppercase and 2 numbers"
-    # or with translated error
-    pattern.error.en = "Provide a room number such as F12: one uppercase and 2 numbers"
-    pattern.error.fr = "Entrez un numéro de salle comme F12: une lettre majuscule et deux chiffres."
-    ```
-    - IMPORTANT: your `pattern.regexp` should be between simple quote, not double.
