Thank you Wolfgang, nice example, ... of code and output, of course.

And even if I use
<code>
\startitemize[n,inmargin]
</code>
I got 2 not in margin. Something similar I know about wrapfig package
for LaTeX. It could 'wrap' text around figure or table while it
couldn't work within list environment (start/stop).

Ok, that only means that I don't understand how lists and this
'environment' work.
