[NTG-context] columnsets and footnotes (better explained)

[Steffen Wolfrum]

Hi Hans,

maybe my problem was not clear enough. So please let me try it once  
more.

The following example has main text in 2 columns and footnote text in  
3 columns:

\setupfootnotes[n=3]
\starttext
   \startcolumns
    \dorecurse{10}{\input tufte\footnote{\input ward \relax}}
   \stopcolumns
\stoptext

But as I also have to use section titles that span the columns  
(without causing pagebreaks)
I need to use columnsets (like they are used in the following example):

\definecolumnset[two][n=2]
\definecolumnsetspan[two][n=2]
\setupfootnotes[n=1,width=\hsize]
\starttext
    \startcolumnset[two]
    \input tufte\footnote{\input ward \relax}
\startcolumnsetspan[two]
   \subsubsection{Spanning all columns without page break}
\stopcolumnsetspan
    \dorecurse{10}{\input ward\footnote{\input tufte \relax}}
   \stopcolumnset
\stoptext


But I don't want the footnotes to be placed at the bottom of each  
column,
I want them to be set in 3 columns at the bottom of the page (as  
shown in the columns example above).

How can this be done?
