    026 * Used to attach validation constraints directly to a property (either the getter or the setter method). The annotation
    027 * value is a comma separated list of <em>validation constraints</em>, each one identifying a validator type (such as
    028 * "required", "minlength") and optionally, a constraint value. Most validators need a constraint value, which is
    029 * separated from the type by an equals size (i.e., "maxlength=30"). In addition, the value may include
    030 * validator macros.
    031 *
    032 * May be placed on any getter or setter method, or on the matching field.
