script.NodeRemoteValue without any attribute?

[nvborisenko]

I am reading the following definition for NodeRemoteValue:

script.NodeRemoteValue = {
  type: "node",
  ? sharedId: script.SharedId,
  ? handle: script.Handle,
  ? internalId: script.InternalId,
  ? value: script.NodeProperties,
}

Hmm, everything is optional? Then what does define it as concrete value? Seems sharedId...

What attributes will be set is specified in the serialization steps https://w3c.github.io/webdriver-bidi/#serialize-as-a-remote-value and depends on parameters like the ownership.
