                                          Specifies one or more graphical elements which
                                          are depicting this data item. 


relative_time                             N       ndt_time

                                          The relative offset of the start time of the scheduled

                                          to" schedule activity. Positive offsets are interpreted
                                          as meaning later in time. 

scheduled_cost                            N       ndt_money

                                          The cost of an activity, estimated in the context
                                          of the schedule. 

schedule                                  MU      schedule

relative_to                                       schedule_activity

                                          Indicates an activity schedule which acts as a
                                          reference for the relative start time of this
                                          activity schedule. 

activity                                  MU      activity

                                          Specifies this activity as being part of a schedule.

                                          this activity schedule as a reference for their
                                          scheduled start times.
