\definereferenceformat[initem][left=\ItemNumber]

Since I don't speak that language, someone could explain why this code doesn't work when I put a stopper in subitemization? The standard dot isn't a stopper itself?

This code seems to work (approximately) like this: it expands the "full" reference, which is: <number> <dot> <number> <dot> and selects "everything from the first dot up to the second one (w/o the dots themselves). So I consider it to be a bit dirty hack (sorry, Wolfgang;)), in a sense that it is not very flexible. If your stopper is, say ")" (and the second one, say, "]", so you have references in a strange form like "1)2]"), you might want to say something like \def\doItemNumber #1)#2]#3\relax (the space after \doItemNumber is gobbled by TeX, so it might be present here or not, it is a matter of taste only). If you have different stoppers, another approach might be reasonable. I can see two possibilities: 1. Get to know _where_ ConTeXt really keeps the relevant info about labels; if the info about the values (w/o stoppers) is preserved, we are saved, if not, we've got a problem; 2. so in the latter case we have to (?) use this kind of hacky solution, which might be something like this (assuming that \stopper and \stopperr are the first- and second level stoppers respectively): \edef\sometemporarymacroname{% \def\noexpand\doItemNumber ##1\stopper ##2\stopperr ##3\relax {\noexpand\doifelsenothing{##2} {##1} {##2}}% }% \sometemporarymacroname (I'm not sure whether the last percentage sign is needed, but a good rule of thumb is to put them everywhere after <closing brace> <newline>, so that the newlines don't get translated into spaces.) I'm not sure whether this works, though, *please* check it and tell me (maybe I'm doing some stupid error, please the TeX gurus correct me if yes). I hope this is ok, though, because then it my first post to this list containing actually an _answer_ and not a _question_:))).
