/**
 * This example demonstrates how to request an exemption for policy violations of a keyword.
 * Note that the example uses an exemptible policy-violating keyword by default. If you use a
 * keyword that contains non-exemptible policy violations, they will not be sent for exemption
 * request and you will still fail to create a keyword.
 * If you specify a keyword that doesn't violate any policies, this example will just add the
 * keyword as usual, similar to what the AddKeywords example does.
 *
 * Note that once you've requested policy exemption for a keyword, when you send a request for
 * adding it again, the request will pass like when you add a non-violating keyword.
