That's actually rather cute.

We have some stuff in-house that generates CDBI classes and SQL CREATE TABLE
statements off a common XML format; it *will* get released eventually but is

it may not help but I should get round to doing it :)

Aye, well, see my 'horses for courses' comment in another post. Analyze
them all and see which works best for you (and tell the respective authors
if you manage to break anything so we can fix it :)
