Hi, XML processing is sort of the rage of the day, and ConTeXt also has some support for it. What I have been wondering is whether luaexpat is on the list of libraries where inclusion into LuaTeX would be considered. Either directly, or as a configuration option when compiling. For processing pure XML files or fragments, this would seem like interesting infrastructure. Another question: I found inclusion of the the Coco patches quite interesting. An application that came immediately to my mind was having a control flow written in Lua that feeds TeX code into the TeX interpreter and works with the result from executing these TeX instructions, by yielding a Lua coroutine until the executed TeX code finally resumes it. Was that the basic intention? Are there any practical experiences with Coco in LuaTeX already? All the best, David -- David Kastrup
