# docbook_setTranslation.sh -- This function standardizes the way

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

# produce the translated instance that is used to expand translation

# markers and produce different output formats.

#

# 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.
