#   render_setLocalizedXml.sh -- This function standardizes the way
Alain Reguera Delgado 2c7b25
#   (.po) translation files are applied to XML files (e.g., .docbook,
Alain Reguera Delgado 2c7b25
#   .svg) in order to produce their related translated instances, used
Alain Reguera Delgado 2c7b25
#   to expand translation markers and produce the final file format in
Alain Reguera Delgado 2c7b25
#   different languages.  Assuming no translation file exists, an
Alain Reguera Delgado 2c7b25
#   untranslated instance is taken from the design model and created
Alain Reguera Delgado 2c7b25
#   (i.e., just a copy) from it.  Using a design model instance
Alain Reguera Delgado 2c7b25
#   (translated or not) is required in order to expand translation
Alain Reguera Delgado 2c7b25
#   markers safely.
