But really, there's no need to use $defs or definitions at all here. Just put it under 'properties' And move the references up a level (i.e. to the node, not a property). > + phy-connection-type: > + # const: "internal" > + allOf: > + - $ref: /schemas/types.yaml#/definitions/string > + - oneOf: > + # There is not a standard bus between the MAC and the PHY, > + # something proprietary is being used to embed the PHY in the > + # MAC. > + - items: 'items' is for arrays, but you just said this is a 'string', not 'string-array'. > + - type: string Already covered by the type $ref.
