Placeholders come back as null, identifiers without their labels
A field that only holds a printed placeholder, such as N/A, TBD or a lone dash, is now returned as null. A required field like that now counts as missing instead of filled.
Invoice and PO numbers lose a leading # or №. Tax IDs lose a printed label such as VAT No: when what follows is clearly the ID. Names and addresses lose trailing commas, and dashes in identifiers and postal codes come back as a plain -.
