- _non-null_ - set to anything to enable feature, in some cases can be interpreted as other types (e.g. path)
- _bool_ - `1`, `True`, `true`, `TRUE` / `0`, `False`, `false`, `FALSE`
- _number_/_size_ - unsigned number, suffixes `MB`, `Mb`, `mb`, `KB`, `Kb`, `kb`
- _string_ - plain string or can have a structure
