11/// # Set
12/// Set is a named group of values of the same type.
13///
14/// - Fapolicyd internally distinguishes between INT and STRING set types.
15/// - You can define your own set and use it as a value for a specific rule attribute.
16/// - The definition is in `key=value` syntax and starts with a set name.
17/// - The set name has to start with `%` and the rest is alphanumeric or `_`. The value is a comma separated list.
18/// - The set type is inherited from the first item in the list.
19/// - If that can be turned into number then whole list is expected to carry numbers.
20/// - One can use these sets as a value for subject and object attributes.
21/// - It is also possible to use a plain list as an attribute value without previous definition.
22/// - The assigned set has to match the attribute type. It is not possible set groups for `TRUST` and `PATTERN` attributes.
