This is planned, though not in the upcoming 1.0, together with
(limited) procedure and trigger support.

This is difficult to do in a database-independent way, esp. because of
the involved query.

This could be supported via attributes to the model elements (which
would contain database-specifc settings), though it requires a change
to the DTD, and thus would need to come after the 1.0.

writeSchemaSqlToFile subtask
which simply outputs the SQL that DdlUtils would use.
