-- Inserts or deletes 'ActivatedRule' objects in a @RuleGroup@ .
--
--
-- You can only insert @REGULAR@ rules into a rule group.
--
-- You can have a maximum of ten rules per rule group.
--
-- To create and configure a @RuleGroup@ , perform the following steps:
--
--     * Create and update the @Rules@ that you want to include in the @RuleGroup@ . See 'CreateRule' .
--
--     * Use @GetChangeToken@ to get the change token that you provide in the @ChangeToken@ parameter of an 'UpdateRuleGroup' request.
--
--     * Submit an @UpdateRuleGroup@ request to add @Rules@ to the @RuleGroup@ .
--
--     * Create and update a @WebACL@ that contains the @RuleGroup@ . See 'CreateWebACL' .
--
--
--
-- If you want to replace one @Rule@ with another, you delete the existing one and add the new one.
--
-- For more information about how to use the AWS WAF API to allow or block HTTP requests, see the <http://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide> .
