-- __For the latest version of AWS WAF__, use the AWS WAFV2 API and see the

-- With the latest version, AWS WAF has a single set of endpoints for
-- regional and global use.
--
-- Returns the status of a @ChangeToken@ that you got by calling
-- GetChangeToken. @ChangeTokenStatus@ is one of the following values:
--
-- -   @PROVISIONED@: You requested the change token by calling
--     @GetChangeToken@, but you haven\'t used it yet in a call to create,
--     update, or delete an AWS WAF object.
--
-- -   @PENDING@: AWS WAF is propagating the create, update, or delete
--     request to all AWS WAF servers.
--
-- -   @INSYNC@: Propagation is complete.
