/**
 * The Range Constraint interface is used to restrict integer and decimal
 * built-in types, or types derived from those.
 * <br>
 * A range consists of an explicit value consists of an explicit value, or a lower bound
 * returned by {@link #getMin()} and an upper bound returned by
 * {@link #getMax()}. <br>
 * <br>
 * Each explicit value and range boundary value given in
 * the range expression MUST match the type being restricted, or be one of the
 * special values "min" or "max". "min" and "max" mean the minimum and maximum
 * value accepted for the type being restricted, respectively
 * <br>
 * <br>
 * This interface was modeled according to definition in <a
 * href="https://tools.ietf.org/html/rfc6020#section-9.2.4">[RFC-6020] The
 * range Statement</a>.
