-- Permanently deletes a < WebACL>. You can\'t delete a 'WebACL' if it
-- still contains any 'Rules'.
--
-- To delete a 'WebACL', perform the following steps:
--
-- 1.  Update the 'WebACL' to remove 'Rules', if any. For more information,
--     see < UpdateWebACL>.
-- 2.  Use < GetChangeToken> to get the change token that you provide in
--     the 'ChangeToken' parameter of a 'DeleteWebACL' request.
-- 3.  Submit a 'DeleteWebACL' request.
