                <!--All group can be in four state: Large->Middle->Small->Collapsed
                    By default group in Large state. When group changes its state it 
                    changes size of all its controls.
      
                    RibbonTabItem has ReduceOrder property. 
                    This property defines order of group to reduce.
                    You can enumerate group names from the last to first to reduce.
          
                    All ribbon contols (Buttons, DropDownButtons, Spinners and so on) 
                    have SizeDefinition property. You can define which size will be used 
                    when group will be in particular state. 
          
                    For example, if you set SizeDefinition = "Middle, Middle, Small"
                    That means:
          
                    Large State of the group -> Middle size of the control
                    Middle State of the group -> Middle size of the control
                    Small State of the group -> Small size of the control
                    -->
