#   render_setLocalizedXml.sh -- This function standardizes the way

#   (.po) translation files are applied to XML files (e.g., .docbook,

#   .svg) in order to produce their related translated instances, used

#   to expand translation markers and produce the final file format in

#   different languages.  Assuming no translation file exists, an

#   untranslated instance is taken from the design model and created

#   (i.e., just a copy) from it.  Using a design model instance

#   (translated or not) is required in order to expand translation

#   markers safely.
