Is it permitted for a UsdLuxDomeLight to have only a `color` and `intensity` input but no `texture:file`? (i.e. to mimic just a flat, global ambient, light)

```auto
    def DomeLight "env_light"
    {
        color3f inputs:color = (0.1, 0.1, 0.1)
        float inputs:intensity = 1
        float3 xformOp:rotateXYZ = (90, 0, 90)
        uniform token[] xformOpOrder = ["xformOp:rotateXYZ"]
    }

```

`usdchecker` does not complain but `usdview` does:

The schema doesn’t explicitly require a texture, but Storm cannot handle dome lights without them. Other renderers may be able to…
