I'm glad I was able to clear that up for you, here's the answer to your follow-up questions:
1. That is correct, though that particular parameter might not be necessary <https://cloud.google.com/appengine/docs/standard/php/config/appref#application>depending on the way you are deploying your application. The app.yaml reference <https://cloud.google.com/appengine/docs/standard/php/config/appref> has a pretty good explanation of each element that can go into it. 2. All services of your application use the default Datastore namespace unless you tell them otherwise <https://cloud.google.com/datastore/docs/concepts/multitenancy>.
