Yes you are correct and I misread the code (it was a overloaded getHandleSet whose format I was not used to). So Type also affects Link uniqueness. >> ...

And seems more appropriate to me... my suggestion was trying to avoid using VersionHandles since I wasn't sure what their status was... Do they act essentially as described here https://extranet.vettalabs.com:8443/bin/view/Novamente/AtomVersionHandles ? (Obviously I can read the code to find out, but it'll aid understanding if my concept of VersionHandles doesn't clash with what the code does.)
