To give a bit of history: expl3 is the result of older work (including complete trial implementations of standalone kernels for testing in various flavors) and was intended to produce a platform for experimentation on top of 2e with the new syntax and models the experimental xpackages have been developed later using variants of that syntax (mainly playing around with alternatives) while at the same time exploring actual new concepts (eg for the OR, the template stuff, frontmatter, ...) --- as a result they have quite different conventions from one module to the next. it is my firm believe after having done (or participated) in these trial developments that a) the original expl3 ideas are sound and better than what was tried as alternatives later on b) that there are a number of glitches in the expl3 that need sorting out c) that to go on from what is there now the experimental code first needs consolidation and normalization thus what i'm doing right now is - converting the existing packages in experimental to expl3 - collecting what i think is needed in terms of change/addition to expl3 i'm in the middle of doing that for xbase, xfrontm, and xor (also alrady wrote up xlang implementing the ideas I presented in Japan on a multi-lingual language model) meaning right now the internals are changing drastically as the packages are not very uniform in their syntax I hope that this normalization is soon ready. I then intend to make that public for discussion as well as opening a discussion on fixing a final expl3 to be used for further work so to answer what to focus on: i'd say expl3 playing with it and joining a discussion of streng and weekness (yes you started that already with our other question) and to look at the explerimental packages only from their implemented functionality (eg the template interface) but not from their internal implementation frank -----Ursprüngliche Nachricht----- Von: Mailing list for the LaTeX3 project [mailto:[log in to unmask]] Im Auftrag von Hendri Adriaens Gesendet: Dienstag, 12.

More specific, I can find some of the work of the first location integrated in some files in the second location, but not everything. What should I be focussing on? Thanks, best regards, -Hendri Adriaens.
