if classCode is just the first letter or letters of the registration number is an element necessary? Can't it just be calculated from the regnum? If there is some processing advantage to having it "precalculated" in the XML, and if the regnum is now going to be an attribute of copyrightEntry (see #5), maybe a regclass attribute could be added as well.
