International Banking Account Number (Microsoft built-in)
Catalogue reference for the Microsoft Purview built-in International Banking Account Number (IBAN) sensitive information type, which detects an International Bank Account Number with a valid country code and mod-97 check digits. Microsoft recommends high confidence (85) for the built-in entity. This YAML-only record lets a package recipe include the Microsoft entity explicitly; it does not reproduce Microsoft's built-in regular expressions, keyword dictionaries, checksums or XML.

- Confidence justification
- Medium confidence for this YAML-only record: its keyword logic finds references to the built-in entity name with Microsoft Purview context, not populated values. Microsoft's own recommended confidence for the entity is 85. The record does not claim to reproduce Microsoft's proprietary detection logic.

Known false positives
- Documentation and policy inventories can mention the Microsoft built-in entity by name. Mitigation: Treat this YAML-only record as catalogue discovery; enable the Microsoft entity for value detection.
- The custom SIT global-iban detects the same data; deploying both doubles matches on the same content. Mitigation: Pick one per package. The custom SIT is the default; include this built-in only by an explicit recipe decision.
