<p>A list of tags that you want to attach to the newly created resource policy. For each tag in the list, you must specify both a tag key and a value. You can set the value to an empty string, but you can't set it to <code>null</code>. For more information about tagging, see <a href="https://docs.aws.amazon.com/organizations/latest/userguide/orgs_tagging.html">Tagging Organizations resources</a> in the Organizations User Guide.</p> <note> <p>Calls with tags apply to the initial creation of the resource policy, otherwise an exception is thrown. If any one of the tags is not valid or if you exceed the allowed number of tags for the resource policy, then the entire request fails and the resource policy is not created. </p> </note>
