App Manifest authors format: wrong example?

> authors contact details of the people or organization responsible for the containers (list of strings)

But the example in [SPEC.md][1] and in [app.json][2] shows one string:

             "authors": "Carly Container <carly@example.com>, Nat Network <nat@example.com>",

I guess the example is wrong.
