/**
* The empty tab list is displayed when there is no selected element in the
* override tests view.
* <p>
* The OverrideTestsView TabbedPropertySheetPage example is a look at the
* properties view after the migration of a TabFolder/TabItem framework to the
* tabbed properties view. In the case of a TabFolder, the folder (provider)
* knows both the tab labels and tab items. This aligns to the tabbed properties
* view, but the tab labels are tab descriptors and tab items are section
* descriptions. This does not work with the default framework as the tabs
* provide the sections. In this case, the IOverridableTabListContentProvider
* framework has been provided.
* <p>
* The overridable tab list is a content provider that provides both the
* sections and the tab labels.
