Editing Attributes in the Structure View
All attributes are displayed in the Structure view. Attributes may be
displayed in blue or black.
  - Attributes whose value can be chosen freely are displayed in black. You
    can edit the value like any other character string.
    
  
- When the attribute value is displayed in blue, you can only change it
    with the Attribute menu. This ensures that only one of
    the correct values is chosen.
