 * EVENT_OR_FACT_CLASSIFICATION := {Size=1:15}

 * A code that indicates the type of event which was responsible for the source
 * entry being recorded. For example, if the entry was created to record a
 * birth of a child, then the type would be BIRT regardless of the assertions
 * made from that record, such as the mother's name or mother's birth date.
 * This will allow a prioritized best view choice and a determination of the
 * certainty associated with the source used in asserting the cited fact.
