I work with Oracle these days, or the ... might contain it - but is it not also missing a NOT NULL constraint? Documentation that conflicts with the DDL makes for an easy code review at least. I look at it more like an interface specification, especially as there are several ways to write DDL - though there should really be a house style. For instance the NOT NULL constraint might be being added later on the script, so it isn't necessarily readable in the same way as normal code.
