Reference documentation and code samples for the Cloud Document AI v1 API enum DocumentSchema.Types.EntityType.Types.Property.Types.OccurrenceType.
Types of occurrences of the entity type in the document. This
represents the number of instances of instances of an entity, not
number of mentions of an entity. For example, a bank statement may
only have one account_number, but this account number may be
mentioned in several places on the document. In this case the
'account_number' would be 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 will
be set to REQUIRED_MULTIPLE.
