Notes:

• Cycleline, haulpath, and warningarea may have zero or more instances.
• Other values have precisely one entry.

The current thinking is that the server traffics in the XML format, while the client applications have helper objects to deal with it. A model is similar to the Bundle class in Android that lets you do things like:

   boolean gpsIsVisible = config.getBoolean("ui.gps.visible", true);
   double blankspeed = config.getDouble("ui.screenblanking.visible", 37.5);

Helper classes for the config object would be coded for Java and C++.

Thinking about XML points out that working with XML is a pain in the butt. The parsers are ugly to work with, and the readability of an XML fragment is not a good as desired. JSON is an alternative that is portable across systems, and much more readable. Here are some thoughts RE: using JSON for the management directive format.
