Link is dead on ​http://www.djangoproject.com/documentation/0.95/models/validation/#model-source-code

This example describes Django version 0.95. For the current example, go here.

This is a variant of #4043, only in this case you've got a link in old docs to something that doesn't exist in current docs instead of the other way around. That example doesn't exist in the current version, likely because model validation doesn't exist in the current version. The docs have gotten better about including invalid links like this (see the last note on #4043) but apparently it's not yet perfect. Fixing up stuff in the old levels isn't going to be a priority, rather fixing the current docs to improve things moving forward is where effort will be spent.
