## STRUCTURED_PAYMENT_REFERENCE

You must identify a structured payment reference present in the document 
in the format "+++000/0000/00000+++", or less frequently just 12 digits.

Extract the 12 digits, and call the setStringIdentification function with stringType=structuredReference to complete the task.

If the structured payment reference is not identifiable, use the setFieldProblematic function to complete the task,
using "ABSENT" as problem type, and providing a description.
