Experimentally, I am finding that the order of the items in the response to a `GET /wiki/rest/api/content/{id}/child` API call is the same as the order in which they appear in the WEB UI.
The API documentation does not actually say anything about the order though, so I am nervous about relying on that.
If the order cannot be relied upon, I see that there is a `position` extension in the results that seems to represent the display order, but that is not mentioned in the API documentation, so I don't know if I can rely on its meaning or continued existence.
Can all of this be clarified in the documentation?
