Generic week view inconsistent with django.utils.dateformat

The generic week view parses the date by passing the year and week to Python's strptime function. The time module, where strptime is from, and specifically the %W directive, operates on an understanding that week numbers range from 00 to 53 and "All days in a new year preceding the first Monday are considered to be in week 0." [See http://docs.python.org/lib/module-time.html].
Django's DateFormat function in django.utils.dateformat operates differently. It uses the ISO calendar and the "first week of an ISO year is the first (Gregorian) calendar week of a year containing a Thursday." There actually is no week 0. Jan 1, 2010 (a Friday) is considered to be week 53 from the year before.
As a result, this makes dealing with week numbers in a template (and passing the correct number to a URL) extremely difficult.
