    043     * In addition to using named layers, it is also useful to be able to define custom user-defined

    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).
