+/**
+ * Diagnostic Command Argument information. It contains the description
+ * of one parameter of the diagnostic command. A parameter can either be an
+ * option or an argument. Options are identified by the option name while
+ * arguments are identified by their position in the command line. The generic
+ * syntax of a diagnostic command is:
+ *  <blockquote>
+ *    &lt;command name&gt; [&lt;option&gt;=&lt;value&gt;] [&lt;argument_value&gt;]
+ * </blockquote>
+ * Example:
+ * <blockquote>
+ * command_name option1=value1 option2=value argumentA argumentB argumentC
+ * </blockquote>
+ * In this command line, the diagnostic command receives five parameters, two
+ * options named {@code option1} and {@code option2}, and three arguments.
+ * argumentA's position is 0, argumentB's position is 1 and argumentC's
+ * position is 2.
