// Returns information about the specified activity type. This includes
// configuration settings provided when the type was registered and other general
// information about the type. Access Control You can use IAM policies to control
// this action's access to Amazon SWF resources as follows:
//   - Use a Resource element with the domain name to limit the action to only
//     specified domains.
//   - Use an Action element to allow or deny permission to call this action.
//   - Constrain the following parameters by using a Condition element with the
//     appropriate keys.
//   - activityType.name : String constraint. The key is swf:activityType.name .
//   - activityType.version : String constraint. The key is
//     swf:activityType.version .
//
// If the caller doesn't have sufficient permissions to invoke the action, or the
// parameter values fall outside the specified constraints, the action fails. The
// associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED .
// For details and example IAM policies, see Using IAM to Manage Access to Amazon
// SWF Workflows (https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html)
// in the Amazon SWF Developer Guide.
