Ok, maybe things have changed. Originally TLC was talking about releasing
parts as files. My understanding is that they have three "quality" levels
of parts: high quality, medium quality, and low-quality. The high quality
parts are what their internal software uses for when they create printed
building instructions. The low-quality parts data are what they give to
third-party game developers. These need to render quickly and don't have to
be accurate. The medium-quality parts data are what I thought would become
the LXF parts. I also believe TLC was considering supplying parts data files
on floppy disk with building sets. But certainly that could have changed over
the years or my memory of this could be faulty.
Jake, certainly you can shed light on this? Is LXF a format for encoding
models only, or can it also specify arbitrary parts? Will an update to the
software itself be required in order to install new parts or will new parts
ship as parts updates? Is the LXF format hierarchical? Can an LXF file
"include" another LXF file by reference or does it actually embed copies of
files? Does LXF stand for LEGO eXchange Format?
Will LEGO provide any LXF-to-XML conversion tools? How about LXF-to-SVG?

I imagine they'll have a big lookup table containing affine transformations
to apply on a part-by-part basis.
