 * An IGT test must be submitted where reasonable.
 
+For historical reasons, non-standard, driver-specific properties exist. If a KMS
+driver wants to add support for one of those properties, the requirements for
+new properties apply where possible. Additionally, the documented behavior must
+match the de facto semantics of the existing property to ensure compatibility.
+Developers of the driver that first added the property should help with those
