/**
 * <p>
 * Provides details of the <code>RequestCancelActivityTask</code> decision.
 * </p>
 * <p>
 * <b>Access Control</b>
 * </p>
 * <p>
 * You can use IAM policies to control this decision's access to Amazon SWF in much the same way as for the regular API:
 * </p>
 * 
 * <ul>
 * <li>Use a <code>Resource</code> element with the domain name to limit the decision to only specified domains.</li>
 * <li>Use an <code>Action</code> element to allow or deny permission to specify this decision.</li>
 * <li>You cannot use an IAM policy to constrain this action's parameters.</li>
 * 
 * </ul>
 * <p>
 * If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action
 * fails. The associated event attribute's <b>cause</b> parameter will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see <a
 * href="http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html"> Using IAM to Manage Access to Amazon SWF Workflows </a> .
