     * However, we generally want the DS lookup to fail for deleted records since for the working website we expect a
     * deleted-flagged record to be as inaccessible as one that is completely deleted from the DB. Any way we look
     * at it, this may lead to integrity problems of the reference index and even lost files if attached.
     * However, that is not really important considering that a single change to a data structure can instantly
     * invalidate large amounts of the reference index which we do accept as a cost for the flexform features.
     * Other than requiring a reference index update, deletion of/changes in data structure or the failure to look
