Israel Varea commented on ATLAS-1839:
-------------------------------------

I can think in a more complex validation when it depends on a different 
attribute. A simple example is when we want to model an Event, with two 
attributes, start_time, end_time. The validation of end_time should be that 
start_time <= end_time.

However, the most common are pattern matching by regular expressions and 
validations from a reference table columns (e.g. country codes).
