 <p>In practice, you should never use the generated functions <code>t_of_json</code> and <code>json_of_t</code> yourself. Most Ohm modules and plugins expect you to provide them with either a format module, or a formatter value. Even when working on your own, using format modules is a superior way of doing things.</p>
 
-<p>A format module provides a type <code>t<.code> along with a handful of ways to serialize and unserialize a type.
