Hi Even,

And what about string list field subtype?
I.e. I need restricted String field to accept only predefined strings 
from the list?
Also for integer or dates fields the value range(s) or time period(s) 
set will be worth adding. I.e. the tube_width (Integer) can only be in  
range 100-183 and etc.
And finally I think the default field value is the subtype 
responsibility too.

Best regards,
