Yes, exactly, but that only if a given sentence is not changed just
because it
"sounds better" with a different word order or with a synonym for a
certain
word.
2 weeks ago I was giving a presentation about OmegaT and OOo document
translations in Tokyo. It was a seminar organized by the Japan Linux
User Association, hosted by Sun Japan. We also had somebody who
presented OLT (Sun's translation tool) and I invited somebody from
W3C to have a thourough explanation about ITS:
http://www.w3.org/TR/its/
ITS is supposed to be implemented for OD files as well, so I am sure
the problem you address above will not be a problem anymore when that
is the case.
Also, I think such issues can be addressed by using rudimentary
"versioning" processes where, in the case of OD, "invisible" styles
could be used for spell/grammar level corrections, revisions,
modifications etc. Such styles could later be easily transfered to
the ITS processes I suppose.
