Class OccurrenceType (2.32.0) 

OccurrenceType(value)

Types of occurrences of the entity type in the document. This represents the number of instances, not mentions, of an entity. For example, a bank statement might only have one account_number, but this account number can be mentioned in several places on the document. In this case, the account_number is considered a REQUIRED_ONCE entity type. If, on the other hand, we expect a bank statement to contain the status of multiple different accounts for the customers, the occurrence type is set to REQUIRED_MULTIPLE.
