051 * In addition to using named layers, it is also useful to be able to define custom user-defined
052 * layers for rendering.
053 * <p>
054 * </p>
055 * Since a layer is defined as a collection of potentially mixed-type features, the UserLayer
056 * element must provide the means to identify the features to be used. All features to be rendered
057 * are assumed to be fetched from a Web Feature Server (WFS) or a Web Coverage CapabilitiesService
058 * (WCS, in which case the term features is used loosely).
