 * and the layer type cannot be determined, then it is represented as an
 * instance of this class.
 *
 * An instance of this class may also be used when loading
 * a [WebMap](https://developers.arcgis.com/javascript/latest/references/core/WebMap/) or a [WebScene](https://developers.arcgis.com/javascript/latest/references/core/WebScene/). If the service
 * of one of the layers in the WebMap/WebScene is not available and the layer
 * type cannot be determined, then it is represented as an UnknownLayer. It is important to note that constructing layers from this class is not supported.
