+If you want to use a specific style multiple times you not have to rewrite it for each text, line, area or symbol rule.
 If you define a style set an `id` and use it with `use` in your rendering instructions:
  - `style-text`

 This example styles all areas with the_residential_ style, which haven't the `highway` or `building` key.
