* The WebExplorer_Module_NavigationList child class queries the |

| 56 |
* |
| 57 |
* It's using the DataSource::Generic chain to access the common |
| 58 |
* backend datasource query API (queryData/querySchema). |
| 59 |
* |
| 60 |
* The results - probably a simple list - are displayed inside |
| 61 |
* a VerticalCSSNavTable by using the AbstractNavigationList. |
| 62 |
* |
| 63 |
* The links contain http query arguments which should trigger |
| 64 |
* the request processor (MVC) to navigate into the selected |
| 65 |
* top-level node. |
| 66 |
* This displays a list of second level nodes inside the content area |
| 67 |
* which are most probably full blown row-based results. |
