I looked at the code quickly and the thing I'm going to ask seems not implemented yet. Sorry if I've overlooked it!

It's about how {% field %} renders boolean tag attributes ("selected", "checked"). It should do:

• in XHTML: selected="selected"
• in HTML: selected

This is because of the way flatatt() works in django.forms.util. I too want to find a way to set an HTML boolean attribute properly with Django.
