I wanted to use `[StudyCompletionDate (0032,1050)]` but since it is retired I would like to know the attribute to be used to determine whether a study is complete or is ready for Archival.

We are writing a archival solution for a PACS server, I would like to query the PACS server for the DICOM images that are marked for archival. I want to know if there is any flag that indicates that a DICOM image is marked for archival.
