I think you're mixing different things here. What I suggested was
support of the database comment statement/clause supported by all major
databases (except maybe SQL Server).
What you're looking for seems to be something similar to the "Domain"
feature of the old Oracle Designer,

This would be an interesting extension as well. Should be possible with
a custom TypeDecorator or TypeEngine.
