I had some success with the following path. It appears that my problem came from the fact that I was not getting the correct value from ::VRMLGenericAtt::getClassType(). It was returning the parent class static _type variable. Things seem to work better if I create a new ClassType in DynamicAttachmentMixin. Is there some reason that this was removed from the code in OpenSG 2.0? Or did it just need to be ported?

I had an experimental fix in my tree that made them work, but I was not
sure if it was completely right. Also I think I had written an example,
will dig both out first thing tomorrow.
