annotate roundup/cgi/TAL/XMLParser.py @ 5267:64ae2108df60
Add section on allowing user access to the labelprop for a class so
that iterating over the class will work.
Ezio found this flaw in the docs while working with the python
tracker.
Mark one other section as Required. Shorten another section heading.
