                                          without stating the functional usage of the equipment.
                                          This is useful for legacy data where there is
                                          knowledge about a piece of equipment but there
                                          is not enough knowledge to define a facility.

                                          activity. For example, a contract may describe
                                          the manner in which this activity is performed.

                                          is kept for this activity. Each compliance instance
                                          defines a specific guideline, limitation, regulation
                                          or privilege and states the status of this activity

                                          storage facility would cause a transient association
                                          to be established.
