Off the top of my head, I think it will be very similar to what needed to be overridden in DynamicDataObjectImpl ... only in DynamicDataObjectImpl, the various eDynamicXXX method assume that the eStaticFeatureCount() method returns 0. I think that if you compare those method implementations to the way it is done in EObjectImpl (which is the SDO 1 base class), I think you'll see what optimizations were added in DynamicDataObjectImpl, based on the knowledge that there are no static features.
Maybe DynamicDataObjectImpl and ExtensibleDataObjectImpl will have enough in common to make DynamicDataObjectImpl extend from ExtensibleDataObjectImpl. Frank.
