Changes between Initial Version and Version 2 of Ticket #36732

-              initial
+              v2
 when enabling i18n on a sitemap, _items uses the following code:
+```python
+{{{
             # Create (item, lang_code) tuples for all items and languages.
             # This is necessary to paginate with all languages already considered.
 …
                 for lang_code in self.get_languages_for_item(item)
+            ]
+```
+}}}
 The list comprehension loads the whole table times the number of languages in memory.
