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