I have passed this in v2 patch, but removed reg in v3 patch since it
is not used.
In v4, I have added back reg = <0> and reg = <1> into the example, and
reg property into schema to fix this error.
Since reg property is not used in the driver, I am not sure whether I
should add it in the schema.
Please let me know which is preferred. Thanks!
