3	3	Referencing the admin docs (https://docs.djangoproject.com/en/1.4/ref/contrib/admin/#multiple-admin-sites-in-the-same-urlconf) and the namespaced URLs docs (https://docs.djangoproject.com/en/1.4/topics/http/urls/#defining-url-namespaces and https://docs.djangoproject.com/en/1.4/topics/http/urls/#url-namespaces) all the admin app instances share the same application namespace (`'admin'`). That's th reason we are using the `'admin:` prefix in the URL names.

5		What allows to differenciate/choose among the URL namespaces of these app instances when reversing named URLs with reverse() (or equivalent ''url'' template tag occurrence) is the value of the ''current_app'' argument. In the case of the admin app it's the `~~`AdminSite.name`~~` value which is the one you can control and which is the one we are passing as ''current_app'' in all calls to reverse().
