  30 * Localization System
  31 *
  32 * This framework handles localization. Localization in new ISSO
  33 * applications is done through this framework. Nearly all strings
  34 * are passed to the string function, which looks up the string in
  35 * a .strings.xml file during runtime. Before release, a C tool
  36 * creates the .strings.xml file for translators. Common strings
  37 * can be accessed through the get lex function which calls a string
  38 * based on unique identifier; this is useful for commonly used strings.
