We have to add accessionCode to all fields in the database. I know, it's a bummer, but it's needed if we are to "see what's new" within an element (taxonObs needs to check for new taxonInterpretations, for example, or commConcept with new commStatus records.)

Some will doubtlessly never be used, but better to have them and not use them than not to have them and need them. That's "bthtanuttnthtant" for short.
