Hi folks, I'm trying to learn the best way to perform complex validations. Take for example a date range on a query, where there is a start date and an end date on the component. I only want to validate both fields if either one is present. If none are present, then it is fine, no validation required. What is the process most folks follow to do custom annotations like this?
