DTD Definition for a Flight Plan

(Not for real use)
Hello!
07/11/2000: New version:
  • I've had to change the order of the group elements. Now is more easy to create an XML Flight Plan.
06/10/2000: First public beta version:
  • I've created this DTD file to share with all the people who are writing a Flight Planner.
  • The Idea is to use a common format for every flight planner and every flight simulator.
  • The actual DTD is a beta 0.1 version. Please send me all your comments.
