I use org-mode 5.21 with xemacs 21.4.21. When I try to use the column features in org -mode, I get a message that emacs 22 is needed for this to work.
Question:
- Is there any patch or something that I can apply to xemacs 21.4 for this work?
- What specific feature in emacs 22 helps this to work?

Thanks,
Jose
