My daughter did a thesis on DID so she has most of my books, but when I get them back I will post references. There is not much at all online about polyfragmentation or complex DID, but it is in the newer DID books that I have purchased that my daughter has away at school right now.
I know in my case it was not meant to mean an additional personality disorder - not that I don't have them, but they have never been discussed or identified. I have DID, severe time loss, and 266 parts including 18 that have been the host. In the past most believed it was from cult abuse, but now we (those that study it) feel it is usually from family abuse that is so severe it seems like it was cult abuse, but it is not.
Here is what I see on the net but there is little out there on those with polyfragmentation on the net, my books do have some, but again not a whole lot.

"The more severe and prolonged the trauma, the more severe the fragmentation."
Richard Kluft----------------------------------------------------------------
The dissociative spectrum (Braun, 1988) extends from normal dissociation to poly-fragmented DID.http://www.fortea.us/english/psiquiatria/spectrum.htm----------------------------------------------
Poly-fragmented DID is an extreme form of DID and involves over 100 personality states. This is often the consequence of sadistic and brutal abuse ... over a long time interval.http://www.urgenttermpapers.com/dissociative.html-----------------------------------------
What is polyfragmentation? The term comes from the root poly, meaning many, and fragments. In complex polyfragmenatation, the survivor will have not only alter systems, but hundreds or even thousands of fragments, isolated parts of their mind created to do a job, and do it well and unthinkingly. Often the job is one that would be abhorrent to the main personality or presenting system. The further away from core beliefs, the greater usually the dissociation and fragmentation that must occur. In other words, a LOT of trauma has to happen to make a person do something that they really don't want to do. And the person has to feel very far away from themselves as well when doing it.

"Extreme versions of DID occasionally develop in response to particularly horrific ongoing trauma with polyfragmentation encompassing dozens to hundreds of personality states. In general, the complexity of dissociative symptoms appears to be consistent with the severity of early tramatization." I am reading The Haunted Self by Van der Hart, Nijenhuis and Steele right now. I will report what they have to say on this as I get farther into the book. This is the BEST book by far that I have read on DID and I have read a lot of them!
