Hi Arthur and Hans,

I make a statement on a part of the Arthur's reply (" there are no real-life examples of documents that use it") : in fact, there are rare examples of such printing materials : scholar editing and printing of Ancient texts are mainly (if I am right) such printing material (including Ancient Armenian or Georgian liturgic hymns). 

An example of such a book : on the even page you read a 'twocolumns' text (say : Greek text with its Latin translation) with there own page setting, including Stephanus apparatus in the footer, and several levels of footnotes within the same footer. Commentaries (in English, French, German, usw) and the like are on the odd page. The average (or regular) situation seems to be less complicated : Greek or Latin text on the even page and translation on the odd page. With Pablo Rodriguez help (actually, this is mainly Pablo's work) I have tried to figure such a goal. But before setting up the even/odd page, there is an issue which one has to fix: the text on two columns is well fitted on the first page, but not on the following pages. How to fix this issue with Greek text on the left column and Latin Text on the right one ? See the mismatch between texts on the second page in the sample below .
Thank you very much for your remarks and advices.

    Définir un `apparat critique' et le mettre en page avec un
    traitement de texte courant est un véritable casse-tête. LaTeX et

    savante, pour la collation et la comparaison de textes

    {\em It is not very easy to define a `criticus apparatus' with some current tools (like Microsoft Office Word or LibreOffice). Maybe \ConTeXt offers some ways that seem easier, in order to improve clear and precise printing.}

    Aequivoca dicuntur quorum \CNote{nomen}{first note} solum

Horum enim solum nomen commune est, secundum nomen vero substantiae ratio diversa; si enim quis assignet quid est utrique eorum quo sint animalia, propriam assignabit utriusque rationem. Univoca vero dicuntur quorum et nomen commune est et secundum nomen eadem substantiae ratio, ut animal homo atque bos.

> 2) Second situation : you want to print a translation on the same page (say the even page) as the original Greek text, with the commentary (or whatever) on the odd page. I fear there is no way to do this at the time (that was impossible with CTX early in 2016). I didn't retry these former weeks...

  Actually, there has been, for quite a long time, a mechanism called
streams in ConTeXt that aimed at doing exactly that.  It’s incomplete
and there are no real-life examples of documents that use it, but I know
that Hans is ready to look into it again provided someone comes up with
a sensible use case, and some details of what should be achieved.
