functions.

For these internal escaping functions, if an action pipeline evaluates to

At parse time the attribute will be treated as if it were just "href".

  optional .k8s.io.apimachinery.pkg.apis.meta.v1.GroupVersionKind responseKind = 2;

  // scope indicates the scope of a resource, either Cluster or Namespaced
  optional string scope = 3;

  // singularResource is the singular name of the resource.  This allows clients to handle plural and singular opaquely.
