Surrogate object attributes (Integration for IBM Rational DOORS)
Each surrogate object always has the following attributes. In addition, attributes are created for additional property types you choose to synchronize.
* 
You can add the surrogate object attributes to your DOORS views.
Integration for IBM Rational DOORS creates two hidden attributes named ART Model Element Type ID and ART Model Element ID. These hidden attributes must not be deleted as they are required by Integration for IBM Rational DOORS.
