[xliff] Unfinished business: phase of alt-trans

Yves and I had a short discussion about the origin of alt-trans and how phase was used. The thread is     http://lists.oasis-open.org/archives/xliff/200210/msg00005.html ([xliff] Thought) and http://lists.oasis-open.org/archives/xliff/200210/msg00009.html. We may want to clear up this issue in our F2F.

cheers,
john
