The Open Source Turning Path Tracker project at Wikia AutoCAD Wiki would
like to export or natively store as LandXML. The data types that need to be
stored are shown below. Does LandXML already provide for these? Could it?

Things the *vehicle* data format must hold:
- Any number of vehicle segments
- Each front driving wheels and (?) centroid or front hitch (tongue?)
point
- For each, the back axle(s) and wheels and (?) centroid
- For each, any back hitch (is hitch the right name for both front and
back connections?)
- For each, any number of other arbitrary points to be modeled
- For each, the maximum allowable angle left and right with the front
wheels or preceding vehicle segment
- For each, the maximum allowable centripetal acceleration for tipping
and slipping
Things the *driving* data format must hold:
- A directional guide in either timed steering (for real-time driving) or
geometric tracking format.
- A forward/backward/speed indicator
- A longitudinal and cross grade indicator representing the entire path
width at the current front of the vehicle
Things the *path* data format must hold (The path data can be conceptualized
as the child of a marriage between a vehicle data set and a driving data
set):
- The entire path in memory, possibly allowing for a drop-once-plotted or
drop-beyond-limit economization of a long path
- The actual state (coordinate or angle value) of every vehicle parameter
at every path representation point
- Time/speed coordinates
- Centripetal acceleration at wheels
- Radial acceleration at wheels
