--
-- __For the latest version of AWS WAF__, use the AWS WAFV2 API and see the
-- <https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html AWS WAF Developer Guide>.
-- With the latest version, AWS WAF has a single set of endpoints for
-- regional and global use.
--
-- Permanently deletes a Rule. You can\'t delete a @Rule@ if it\'s still
-- used in any @WebACL@ objects or if it still includes any predicates,
-- such as @ByteMatchSet@ objects.
--
-- If you just want to remove a @Rule@ from a @WebACL@, use UpdateWebACL.
--
-- To permanently delete a @Rule@ from AWS WAF, perform the following
-- steps:
--
-- 1.  Update the @Rule@ to remove predicates, if any. For more
--     information, see UpdateRule.
--
-- 2.  Use GetChangeToken to get the change token that you provide in the
--     @ChangeToken@ parameter of a @DeleteRule@ request.
--
-- 3.  Submit a @DeleteRule@ request.
