As mentioned in my previous post, I have some concerns about the actual contents. Actually, I only really have one concern. The section describing the sub-files in the MPD isn't appropriate for included unofficial parts. I believe that included unofficial parts should be included in the file exactly as they appear on the Parts Tracker (if they are on the Parts Tracker), or exactly as they are supposed to appear on the Parts Tracker (if they are not on the Parts Tracker). So it might look like so:
0 FILE <Filename>.dat
0 ~Electric Mindstorms NXT Battery Lid
0 Name: 54708.dat
0 Author: Philippe Hurbain [Philo]
0 !LDRAW_ORG Unofficial_Part
0 !LICENSE Redistributable under CCAL version 2.0 : see CAreadme.txt
0 BFC CERTIFY CCW
0 !HISTORY 2007-12-07 [Philo] Creation
Where <Filename> is the modified in-the-MPD filename.
