57     * The WebExplorer_Module_NavigationList child class queries the
58     * backend for a list of known nodes at toplevel.
59     *
60     * It's using the DataSource::Generic chain to access the common
61     * backend datasource query API (queryData/querySchema).
62     *
63     * The results - probably a simple list - are displayed inside
64     * a VerticalCSSNavTable by using the AbstractNavigationList.
65     *
66     * The links contain http query arguments which should trigger
67     * the request processor (MVC) to navigate into the selected
68     * top-level node.
69     * This displays a list of second level nodes inside the content area
70     * which are most probably full blown row-based results.
71     * (ms-lingo: recordsets)
