<!-- XML description file for the DIS-2012 (Final DIS version 7) protocol. Some classes require manual clean up and intevention. -->

<!-- This file is used by XMLPG, a fairly simple program that processes this XML file and generates
     a programming language source file, for example Java or C++. Almost all the work of writing a
     protocol is boilerplate. Getters and setters for fields, marshalling and unmarshalling, and
     so on. Once we have a description of the protocol that can be processed by automated tools the
     actual work of writing the protocol is straightforward, and we can let the tool do almost all
     the work. There are a few possible issues, such as unit confusion, but for the most part this
     gets us 98 percent of the way there, and we can fix any issues in the generated source code
     with patches. 

     The syntax is fairly straightforward. We define objects with their fields (type, name) and 
     can specify inheritance. Classes and fields can have comments. There are lists of objects,
     of either fixed or variable length. The variable length lists include a reference to a field
     that tells us how long the list is.

     annotations here are used only by XMLPG, the source code generation tool.

       ######### Sir, Here are the sections that were designated to me. The logistics part (7.4.2 & 7.4.3) were only modified minumally.
       #########     For the "primitve types" through out the sections I could not find when I should assign a "default value", so I left them
       #########     either unassigned with no value, or, If I could see in your previous code where you assigned them I did the same. If there are
       #########      corrections or any additional items to address I will impliment them.
