Does anybody have a minimal working example on this topic? Because of the
concise syntax "prefix=+" it is difficult to google for an example.

This feature is mentioned in two places:
1. contextref.pdf in section "12.5 Cross references" explains the main
mechanism but seems a little outdated.
2.  Hans Hagen, "This Way - Cross document referencing", September 2011.
This is more up to date, but mentions the feature only briefly. The
mentioned key there is not "prefix" but "referenceprefix", which doesn't
seem to work either.
