25.6.3. Disabling Portlet Decoration

One possible use of window properties is demonstrated in the divRenderer RenderSet implementation. If a window definition (in the portal descriptor) contains a property like:
      <!-- turn the decoration off for this portlet (i.e. no title and mode/state links) -->
the DivWindowRenderer will use the decoration renderer from the emptyRenderer RenderSet to render the decoration for this window (not delegate to the DivDecorationRenderer). As a result, the portlet window will be part of the rendered page, but it will not have a title, nor will it have any links to change the portlet mode or window state.
