  accTitle: Authority, certainty, exposure and personal data
  accDescr: A document or claim is classified on four scales: authority, by decision maker and state; certainty, by source and result; exposure, by harm from disclosure; and personal data, by data type. Dashed arrows warn that authority does not determine certainty, certainty does not determine exposure and exposure does not replace personal-data classification.
