/**
 * Keyword digesters
 *
 * <p>Digesters play two important roles:</p>
 *
 * <ul>
 *     <li>they detect similar schemas for a given keyword, and produce the same
 *     output in this case;</li>
 *     <li>they provide to later elements in the validation chain the list of
 *     types validated by a keyword.</li>
 * </ul>
 *
 * <p>The first item has two advantages: not only is the library's memory
 * footprint reduced, it also allows a great simplification of keyword
 * constructors.</p>
