The Django documentation is very minimal and I can't seem to get this to work.

Currently I have 3 individual sitemaps, and I would like to create a sitemap index for them:

(r'^sitemap1\.xml$', 'django.contrib.sitemaps.views.sitemap', {'sitemaps':sitemap1}),
(r'^sitemap2\.xml$', 'django.contrib.sitemaps.views.sitemap', {'sitemaps':sitemap2}),
(r'^sitemap3\.xml$', 'django.contrib.sitemaps.views.sitemap', {'sitemaps':sitemap3}),

The Django documentation mentions adding something along the lines of:

url(r'^sitemap-(?P<section>.+)\.xml$', views.sitemap, {'sitemaps': sitemaps},name='django.contrib.sitemaps.views.sitemap'),

What is "section" in this case? And how do I access this index file? Is it downloadable or is it accessible via a url?

Any help is greatly appreciated!

Edit Basically I would like to accomplish this in Django: https://support.google.com/webmasters/answer/75712

If you included the app with a namespace (e.g. include('myapp.urls', namespace='myapp'), then you need to include the namespace when reversing, e.g. {% url 'myapp:my_url_name' %} or reverse('myapp:my_url_name').

url(r'^sitemap-(?P<section>.+)\.xml$', cache_page(86400)(views.sitemap), {'sitemaps': sitemaps}, name='sitemapsname'),
url(r'^sitemap\.xml$', cache_page(86400)(views.index), {'sitemaps': sitemaps, 'sitemap_url_name': 'posts:sitemapsname'}),

note: posts:sitemapsname is my app
