KEY      TYPE            VALUE

D        name            (Optional) A name specifying the circumstances under which the annotation
                         should be deactivated. Valid values are:
                            PC        The annotation should be deactivated as soon as the page is closed.
                            PI        The annotation should be deactivated as soon as the page
                                      containing the annotation becomes invisible.
                            XD        The annotation should remain active until explicitly deactivated by
                                      a script or user action.
                         Note: At any one time, only a single page is considered open in the viewer applica-
                         tion, even though more than one page may be visible, depending on the page lay-
                         out.
                         Default value: PI.

DIS      name            (Optional) A name specifying the state of the artwork instance upon deactiva-
                         tion of the annotation. Valid values are U (uninstantiated), I (instantiated), and
                         L (live). Default value: U.

                         Note: If the value of this entry is L, uninstantiation of instantiated artwork is not
                         required unless it has been modified. Uninstantiation is never required in non-in-
                         teractive applications.

TB       boolean         (Optional; PDF 1.7) A flag indicating the default behavior of an interactive tool-
                         bar associated with this annotation. If true, a toolbar should be displayed by de-
                         fault when the annotation is activated and given focus. If false, a toolbar should
                         not be displayed by default. Typically, a toolbar is positioned in proximity to the
                         3D annotation.
                         Default value: true.

NP       boolean         (Optional; PDF 1.7) A flag indicating the default behavior of the user interface
                         for viewing or managing information about the 3D artwork. Such user interfac-
                         es can enable navigation to different views or can depict the hierarchy of the ob-
                         jects in the artwork (the model tree). If true, the user interface should be made
                         visible when the annotation is activated. If false, the user interface should not
                         be made visible by default.
                         Default value: false

      The A and D entries of the activation dictionary determine when a 3D annotation
      may become active and inactive. The AIS and DIS entries specify what state the as-
      sociated artwork should be in when the annotation is activated or deactivated. 3D
