4 If there is a hold on a copy, Evergreen will now return to SIP a hold id to
5 indicate that the copy has been captured for a hold. One possible use case for
6 this feature is a scenario where a delivery vendor may be sorting copies needed
7 for holds into a different bin from copies returning to their home library. The
8 presence of the hold ID indicates that the copy has been captured for a hold.
9 It also could use for an Automated Materials Handling (AMH) System to indicate
10 that the copy is needed to fill a hold.
