Greetings! I am currently editing several XML files which are the chapters of a Tamil thesaurus, and each file is dangerously close to the size limit connected with the script specificity. ("support for RTL languages" has to be activated, for proper display, and I have already increased the default size beyond which RTL language support is automatically deactivated) I would appreciate pointers on the best methods for dealing with the larger entity, i.e. the sum of the chapters. Can I create a MASTER document in Oxygen in which the chapters are INCLUDED (by mentionning their names) for the sake of processing the sum of the chapters? (I currently run XSLT transformations on separate chapters for making indices? How to do that for the sum of the chapters?) Thanks for any pointers to the appropriate section inside the Oxygen documentation (provided that it is possible to do that in Oxygen ...). If the "RTL language" limit was not there, I would have used a single file but that does not seem to be possible. -- Jean-Luc Chevillard (Paris-Pondicherry-Hamburg) "https://univ-paris-diderot.academia.edu/JeanLucChevillard"
