Description

Let's assume there are two entity types A and B. For A the entity set As exists. A has two navigations toChildren, as A builds up an hierarchy, and toB. In this case a client can send GET request like the following:

.../exampleService/As?$expand=toChildren($level=1;$expand=toB)&$top=1

The expected response would look like this

{
  "@odata.context": ".../exampleService/$metadata#As(toChildren(toB()))",
  "value": [
    {
      ...
      "toChildren": [
        {
          ...
          "toB": {
            ...
          },         
        },
        {  ...
         "toB": { ... },
        }
      ]
    }
  ]
}

Infect the response does not contain the navigation to B evenso the data are provided
