XX. Generating HTML forms from models
This is mostly just a reworking of the ``form_for_model``/``form_for_instance``
tests to use ``ModelForm``. As such, the text may not make sense in all cases,
and the examples are probably a poor fit for the ``ModelForm`` syntax. In other
words, most of these tests should be rewritten.
