--
-- __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.
--
-- Attaches an IAM policy to the specified resource. The only supported use
-- for this action is to share a RuleGroup across accounts.
--
-- The @PutPermissionPolicy@ is subject to the following restrictions:
--
-- -   You can attach only one policy with each @PutPermissionPolicy@
--     request.
--
-- -   The policy must include an @Effect@, @Action@ and @Principal@.
--
-- -   @Effect@ must specify @Allow@.
--
-- -   The @Action@ in the policy must be @waf:UpdateWebACL@,
--     @waf-regional:UpdateWebACL@, @waf:GetRuleGroup@ and
--     @waf-regional:GetRuleGroup@ . Any extra or wildcard actions in the
--     policy will be rejected.
--
-- -   The policy cannot include a @Resource@ parameter.
--
-- -   The ARN in the request must be a valid WAF RuleGroup ARN and the
--     RuleGroup must exist in the same region.
--
-- -   The user making the request must be the owner of the RuleGroup.
--
-- -   Your policy must be composed using IAM Policy version 2012-10-17.
--
-- For more information, see
-- <https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html IAM Policies>.
--
-- An example of a valid policy parameter is shown in the Examples section
-- below.
