No problem since \startbackground has a number of other problems
as well (esp. regarding float placements) that I'd be happy to get
away from, but (never having used textbackgrounds seriously before)
is there a simple way to get the equivalent of

   \setupbackground[frame=off,leftframe=on]

using textbackgrounds?

My previous set of definitions was:

%D how examples look

\defineenumeration
	[Example]
	[style={\switchtobodyfont[9pt]},
          headstyle={\ss\bf},
          before=,
	 after=,
          inbetween=\noindent,
          text=Voorbeeld,
          indentnext=no,
          indenting=yes,
          chapternumber=yes]

\def\startexample%
   {\blank
    \start
    \setupbackground
       [frame=off,
        leftframe=on,
        offset=0pt,
        width=broad,
        background=,
        rulethickness=2pt,
        framecolor=examplecolor]
    \startbackground
    \startnarrower[left]
    \startExample  }

\def\stopexample%
   {\stopExample
    \stopnarrower
    \stopbackground
    \stop
    \blank }
