Hi Tassilo,

the only way to understand this paragraph is historical.

In the early days of BEAMER export, Eric Fraga invented a way to make  
columns
using an additional level of outline structure, just for making the  
columns.

http://thread.gmane.org/gmane.emacs.orgmode/19895/focus=19895

This worked, but made it difficult to export this file in
any other way, because of the extra structure.  This was overcome
with the BEAMER_col property, and this is what this paragraph
and the phrase "without additional structure" is referring to.

The "tutorial" I wrote on worg is out of date and bad, maybe we should  
remove it?
Does someone (Eric Fraga?) have time to check if there is anything  
interesting
in there that is is still true and not covered by the manual or by  
Eric's
tutorial?  If not, we should remove this outdated document.

If it adds something, maybe we can move that information?

If that is done, maybe we should remove this document.

Thanks

- Carsten
