Hi, I uploaded beta zip with a prelude to the new structure related code. I hope that I didn't forget files. context --make xp will generate the experimental format (you really need a luatools --generate because there are many new files). With context --interface=xp yourfile will use that format. Eventually the xp format will go away but this is a nice intermediate step for those who are willing to help debugging the code. Those who look into the source ... it all happens in strc-*.tex|lua and when you look in the tua/tuc file you see what is carried around (this will be optimized). Much code still needs a rewrite. The format file is slightly smaller and less hash space is used, in spite of more functionality. This is a side effect of a more dynamic inheritance model (slower, but not so much an issue noaways and compensated by speedups in other areas like one time multipass data reading). For xml users: although somewhat experimental, we now have roundtrip xml in lists (and some other constructs, more to come). \setuphead[chapter][expansion=xml] This only works for mkiv xml, as we also keep track of the document root in order to apply the right setups. For Aditya: numbering of math is redone and soon we have to split up strc-mat into pieces (when we start doing unicode math) but you can already have a look at it. Don't worry too much if your documents crash. I simply cannot test everything so it might be a good opportunity for volunteers to help documenting behaviour and making tests. The main incompatibilities are in the numbering: we now use sets for numbering, seperators, converters etc as well as processors for specific layout of these thingies. This info is carried around so that intermediate style changes are reflected in tables of contents and references (of course they can be overloaded). It's the price we pay fro more flexibility.
