the shift of <Object> is active : Bool (assertion)

If “report shift activity” is set to true for some object with a shift assigned to it, then when that shift is active the assertion “the shift of <Object> is active” will be made (and when the shift is inactive the assertion will be retracted). You can set or unset the ‘shift is active’ assertion for all objects of a particular type by using the global mechanism in SERVICE PARAMETERS to set default values for all members of the chosen type.
