Hi Arthur,
Thanks a lot for your advise. I'm looking forward to the mechanism you're talking to (streams) and I don't give up for testing a useful kind of typesetting where the goal is to place 2 or 3 parallel paragraphs into columns on the even page (e. g. mainly greek & latin & modern language) with 'criticus apparatus' on different levels in the footnotes, with commentary on the odd page.
It seems that this combination with specific rulles for the even page (where the 2 or more parallel paragraphs are defined) aims some complex difficulties (because we have to synchronize the odd page text in facing the left page's text). There are some examples with LaTeX reledmac commands here : https://www.ctan.org/tex-archive/macros/latex/contrib/reledmac/examples (work done by Maieul Rouquette and alii).
I've founded enumerations of such issues in order to compose a text on a double page with 'reledpar' and 'reledmac' packages in LaTeX here : http://distrib-coffee.ipsl.jussieu.fr/pub/mirrors/ctan/macros/latex/contrib/... (the document is 126 pages long). And for 'reledmac' package : ftp://ftp.dante.de/tex-archive/macros/latex/contrib/reledmac/reledmac.pdf (422 pages).
I'll try to make some 'meaningful feature' step by step, in order to clarify what kind of issues we are confronting to. At the moment, the main issue would be to fix the parralel text (greek/latin) on the same columns on following pages in a page with footnotes (because the greek text - or latin - don't stay at the right place).
Well, whatever the whole problem is, thank you very much to help me to clarify the situation.

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).
That’s not what I meant. There is an experimental mechanism in ConTeXt called streams that could be part of the solution to your problem, but there are no publicly available documents that make use of it. The commands for creating and managing streams are in the file page-str.mkiv; there are short examples at the end. I mention this because this is typically the kind of issue that need serious input from users in order to become a meaningful feature.
