#   This function standardizes the way (.po) translation files are
Alain Reguera Delgado 2e37b0
#   applied to XML files (e.g., .docbook, .svg) in order to produce
Alain Reguera Delgado 2e37b0
#   their related translated instances, used to expand translation
Alain Reguera Delgado 2e37b0
#   markers and produce the final file format in different languages.
Alain Reguera Delgado 2e37b0
#   Assuming no translation file exists, an untranslated instance is
Alain Reguera Delgado 2e37b0
#   taken from the design model and created (i.e., just a copy) from
Alain Reguera Delgado 2e37b0
#   it.  Using a design model instance (translated or not) is required
Alain Reguera Delgado 2e37b0
#   in order to expand translation markers safely.
