Spain Driver's License Number
Detects Spain driver's license number patterns. This pattern is based on a Microsoft Purview built-in sensitive information type. Users already running Purview may prefer to enable the built-in SIT directly, or use this version as a starting point for customisation.

- Confidence justification
- Medium confidence: pattern has structural constraints but corroborative keywords are recommended to reduce false positive rates. Note the format overlaps with Spanish DNI numbers. Added context gating and exclusion rules improve precision and reduce incidental matches.

Known false positives
- Spanish DNI (national identity document) numbers share the same format of 8 digits followed by a letter, making it impossible to distinguish between DNI and driver's license numbers by format alone. Mitigation: Require corroborative evidence keywords specific to driver's license context within the proximity window.
