It doesn't. The schema says 'pon' is the 3rd entry in reg-names. As 'reg-names' is new I thin this should be: items: - const: hlos - const: pbs And if there's 1 entry, then 'reg-names' should not be there. Rob

With this being the case would the following be acceptable? minItems: 1 maxItems: 2 items: anyOf: - const: pon_hlos - const: pon_pbs - const: pon If not we would be ok with getting rid of the reg-name property.
