/// <summary>
/// Specifies whether the list must have an item selected at all times.
/// </summary>
bool ISelectionProvider.IsSelectionRequired
{
    get
    {
        return true;
    }
}

This property can be dynamic. For example, the initial state of a control might not have any items selected by default, meaning that IsSelectionRequired is false. However, after an item is selected, the control must always have at least one item selected.
