The goal here was to piggy-back on top of rather than co-opt > regular Org-mode syntax. I understand that argument. It's just that the current solution is not optimal (among others) for documents mixing R and shell code: you don't want your "session" property to be common between both languages (shell code sent to your R terminal, or vice-versa). But it's nice this case is already handled in a more generic way than on the code blocks themselves, and I can live with that. Thanks again for your help. Best regards, Seb -- Sebastien Vauban
