to the original poster...I see by your profile you are in the UK...a bit of information here in America we dont have something called DID traites. we have the general category of dissociative symptoms....

any one of any mental disorder or not can have dissociative symptoms.

example a person with PTSD can have the dissociative symptoms of feeling numb, spaced out, disconnected from their body or their environment, hear voices, or even have parts of self, dissociative type parts....

here in america DID is not a specturm (by that I mean we dont have different types of DID or different levels of DID like for example autism has many different types of autism or like psychotic disorders have more than one schizo type disorder that includes schizophrenia.) we have one mental disorder called DID and either a person meets the full diagnostics for it and gets the label or they dont meet the diagnostic criteria and do not get the diagnosis.

that said the general term dissociation is a spectrum meaning with in that category there are many dissociation levels and disorders.

you can find more information about what America goes by for what is DID in the link in my signature line.

keep in mind that this is only for america. your location of the UK may go by different standards so to find out whats what in your location you will need to contact a treatment provider in your off line location.

for those asking about DDNOS here in america DDNOS is broken up into many different mental disorders now. some was added to PTSD, Some was added to Depression, Some DDNOS symptoms are now covered by Dissociative Amnesia, depersonalization/derealization disorder, and DID, some was split into two new disorders called OSDD (other Specified Dissociative Disorder) and USDD (Un Specified Dissociative Disorder)

short version those with the diagnosis of DDNOS must nowe consult their treatment providers who will tell them what their new diagnosis's are and which one of their DDNOS symptoms are covered by what disorder now.

for example I know someone who was previously diagnosed DDNOS and now their diagnosis's are bipolar disorder, Anxiety, depression, Schizophrenia, PTSD and dissociative Amnesia.

because of the extensiveness of how the American Psychiatric Association broke up DDNOS into other categories\diagnosis's only your treatment providers can now say where you fit in with the new diagnostics.
