The Original BaseFeature implementation had some serious issues with scoped links. It failed completely for e.g. sketches on the BaseFeature as it made a local link to refere to a out of body object. The only solution to make this work correctly is to add a proxy object into the body which is alloed to exactly that, to link outside oof the body. Something like shapebinder.
