Can someone elaborate on the "what is done" for the menu items of the
tabbed pane items.
The functionality is often more durable than the actual UI behaviour ,
so it may be important
To be explicit about what functionality is expected . It can be
something like:
System Function                                              Use case
1 Pathology request: re -order item.                     The system
re-orders the given request item by 
a.printing a request form
b. placing a message on the reliable messaging subsystem to the
pathology provider.
2 Pathology request: Graph                                The system
inspects the request item and FOR EACH  unit test item, 
looksup the previous request items for matching unit item types , and
places them in
keyed collections of values , keyed by unit type. ( Sorry , too much
implementation detail here).
You can also specify pre and post conditions : eg.
For 1.  precondition:  There exists no current re-order , or the user
manually confirms re-order.
            Postcondition:  a re-order with no result association is
created. A promise acknowledgement exists in the message subsystem for
                                    Delivery of the re-order.
For 2.  precondition:  the system recognizes the item as a graphable
            Postcondition:  maps of values of each unit graphical item;
range of values graphed for each graphable type.
