The chances are very very good that in 99% of the cases we'd only ever
have a single title. multiple titles would be rare. and, to make it worse,
there are several instances of this where you need a table but its seems
overkill for the odd 1% time when you actually need teh extra row.
of course, the there'd be a language lookup table.
