  * DTD for installer descriptor files.
  *
  * Installer descriptor files list the set of XML database schema and data
  * files to parse and execute during installation.
  *
  * All file paths are relative to the location of this file.
  *
  * Note that for locale-specific data files, the string "{$locale}" appearing
  * in a file path will be replaced with the default locale selected at
  * installation time. Similarly, "{$installedLocale}" will be replaced with
  * each locale to be installed (i.e., that file will be installed for each
  * selected locale).
  *
  * Example:
  *
  * <install version="2.0.0.0">
  *    <schema file="ojs_schema.xml"/>
  *    <data file="data/common_data.xml"/>
  *    <data file="data/locale/{$locale}/locale_data.xml"/>
  * </install>
