The example above seems to illustrate rather more points than
just \definestartstop. Nevertheless, thanks.

Another point: is somebody willing to take the trouble to give me a
complete rundown of all the parameters of \setupitemize and
\setupenumerations? I have been playing around a bit with these
commands but am not making much headway; many parameters don't seem to
have any effect at all.

In particular, I want to make numbered and bulleted lists in which the
number or bullet is formatted as a run-in head, and items are
separated by vertical space.
