[xliff] Thought

Hi all,

I just had a thought.
XLIFF uses <alt-trans> to provide two types of information: pre-translated
material, and old version of the translation (change tracking). However
there are no specified way of distinguishing between which <alt-trans> is
what. We probably need to add some guidelines in the specification for this.
For example: any <alt-trans> with a match-quality attribute is a proposed
translation, if not and has a phase reference in its <target> element, it's
a old translation being kept track of. Or something of that effect.

At some point tools will have to implement this. How would you see this
done?

Cheers,
-yves
