Cam,
I could imagine defining a derived unchangeable feature that would use
the value of another feature to do a lookup in some table or properties
file, but no such mechanism exists today. I.e., I can imagine doing
this at the level of the model, but not so much as something done during
loading, since the inverse would clearly need to be done during saving.
That being said, in general, it seems best to have the data be the same
for all languages and to have translations be something left to the
viewing mechanisms. Consider, for example, if databases support what
you've just described. A better approach might be to define an
enumeration and to provide translated strings that correspond to those
literals; the item providers generate a key for each enumeration literal
that can be translated and is used in the properties view...
