 /**
+ * This class is a support fragment for creating tree views in JavaFX Controls. It provides the view
+ * counter part of a {@link DynamicTreeContentProviderBase}. The content provider is responsible
+ * for selecting elements from a base model and ordering them acc. to a custom defined structure.
+ * These two fragments have to be combined in a JavaFX controller inheriting from the base class
+ * {@link AF3FXViewPart}.
+ * <p>
  * TreeViewer that constructs a DynamicTreeViewer whose UI provider uses the methods and kernel
  * services for {@link IHierarchicElement}s and {@link INamedCommentedElement}s.
  * The Viewer uses a composition principle where a client must provide a {@link TreeView} (JavaFX),
