After all a lot of the documentation therein was provided by us during the last years before that its internal documentation was very much out of date (still is in some parts). what i mean is, you need to have got a feeling for it but that it true right now as well except that right now because of nearly no conventions people are forced to reinvent the wheel over and over just because they don't know that some command or datatype or whatever already exist somewhere. so yes you need a re-think, you probably don't need much of a rewriting for an existing package if you just mainly do a manual translation but you can gain a lot once you start replacing all you low-level private code by already provided solutions for many of the basic functionality which right now is often repeated over and over again in packages.  > Clearly I haven't yet got my brain around what one is supposed to do  > with all of the new data types (prop, seq, tlp) - and I doubt anyone  > else listening has.
