Documentation mismatch regarding "Many-to-one relationships that can be null"

[misc@…]

​http://www.djangoproject.com/documentation/models/many_to_one_null/ say
"To define a many-to-one relationship that can have a null foreign key, use ForeignKey() with null=True "

However, ​http://www.djangoproject.com/documentation/model_api/ says that this is blank=True that should be used.

I can't find the part of docs/model_api that you're talking about.
