Hi All,
I am trying to design my schema using composite column. One thing I am a bit confused is how to define validation_class for the composite column, or is there a way to define it?
for the composite column, I might insert different value based on the column name, for example
I will insert date for column "created": 

set user[1]['7:1:100:created'] = 1351728000; 

and insert String for description

set user[1]['7:1:100:desc'] = my description; 

I don't see a way to define validation_class for composite column. Am I right?

Thanks.
