A Row object does not know its db table (and therefore fields), so it would not be able to run validations. If you really need to validate a set of values outside the context of doing an update, it wouldn't be difficult to write a convenience function to do so (just pass in the db table, iterate through the fields, and call the Field.validate method on each value).
