# render_doTranslation.sh -- This function standardizes the way

# translation files are applied to design models in order to produce

# the translated instance that is used to expand translation markers

# and produce the base-rendition output.

#

# Assuming no translation file exists, the an untranslated instace

# from the design model is created (i.e., just a copy of it). Using a

# design model instance (translated or not) is required in order to

# expand translation markers safetly.
