Thanks Andreas!
By looking at the MDR implementation I concluded that there isn't a simple
access method to do what I want in MDR so MDR uses some kind of search
mechanism through the model that I don't fully understand.
After that I searched for the simple access method in uml2 and tried to find
some kind of search mechanism in the uml2/emf to either find all
ElementImports and filter them to get the ones that are connected to the
PackageableElement (brute method) or something smarter. I couldn't figure
out how this is done since I don't know enough of the uml2/emf API.
