/**
 * The {@code Priority} annotation can be applied to any program elements
 * to indicate in what order they should be used.
 * The effect of using the {@code Priority} annotation in
 * any particular instance is defined by other specifications that 
 * define the use of a specific class.
 * <p>
 * For example, the Jakarta Interceptors specification defines the use of
 * priorities on interceptors to control the order in which
 * interceptors are called.</p>
 * <p>
 * Priority values should generally be non-negative, with negative values
 * reserved for special meanings such as "undefined" or "not specified".
 * A specification that defines use of the {@code Priority} annotation may define
 * the range of allowed priorities and any priority values with special
 * meaning.</p>
