handle_keyword_policy_violations
=head1 DESCRIPTION
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 add_keywords.pl 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.
