Hi,
yeah, I am okay with design prudence, just used to be so paranoid about performance that just any possible "one more thing to do" gets me nervous :) Language versions do exist, say Dutch has different orthography depending on what convention is used, so you may well need to suddenly add a further level of definition. But you can pretty much do that by a sequence of alter tables, especially in a situation like this.
Oh well, we are discussing principles as applied to a practical situation that we actually ignore, so...
It's been a pleasure, but unless we get more detail... not much we can do apart from putting out personal preferences :)
Bèrto
