I had some offline discussion with Laurent about this since, the logical 
conclusion of this would be anything from 
schemas/media/video-interfaces.yaml# would be valid.

And I'll admit I looked @ upstream examples and copied/pasted which also 
implies that the upstream examples aren't correct.

So, I'll v6 this with

    properties:
      endpoint:
        $ref: /schemas/media/video-interfaces.yaml#
        _additionalProperties_: false

        properties:
          link-frequencies: true
          data-lanes:
            oneOf:
              - items:
                  - const: 1
                  - const: 2
              - items:
                  - const: 1
                  - const: 2
                  - const: 3
                  - const: 4

        required:
          - data-lanes
          - link-frequencies

and then change the relevant upstream examples of unevaluatedProperties: 
false to additionalProperties: false.
