  9. This sitemap object initializes on a feed dictionary (as would be passed
  10. to `django.contrib.syndication.views.feed`) and a slug dictionary.
  11. If the slug dictionary is not defined, then it's assumed the keys provide
  12. the URL parameter to the feed. However, if you have a complex feed (e.g.,
  13. you override `get_object`, then you'll need to provide a slug dictionary.
  14. The slug dictionary should have the same keys as the feed dictionary, but
  15. each value in the slug dictionary should be a sequence of slugs that may
  16. be used for valid feeds. For example, let's say we have a feed that
  17. returns objects for a specific ZIP code in our feed dictionary:
  18. feed_dict = {'zipcode' : ZipFeed}
  19. Then we would use a slug dictionary with a list of the zip code slugs
  20. corresponding to feeds you want listed in the sitemap:
  21. slug_dict = {'zipcode' : ['77002', '77054']}
