The navigationPane component creates a series of navigation items representing one level
in a navigation hierarchy. These items may either be added as children or a menu model may be bound to the
navigationPane component. If a menu model is bound, of class org.apache.myfaces.trinidad.model.XMLMenuModel or
org.apache.myfaces.trinidad.model.MenuModel, a level along the focus path, or the next level down, will be
rendered. A node that is on the focus path will be rendered as "selected"
