 * This interface can tell anyone if this property is a greater value than the
 * other property.
 *
 * <p>A credential is a property with intersection and union rules defined on it.
 *
 * <p>A credential is a product or sum of credentials. A product of credentials
 * is applies all at once. A sum of credentials can be applied one term by one.
 *
 * <p>For example, a*b != a, but a+b == a.
 *
 * <p>Now a role is a product of a property RoleType and a property RoleValue: t*v.
 * When expiration time is introduced, another term is inserted in the product:
 * t*v*e.
