What is the primary purpose of validation groups in a SAIL interface?

The primary purpose of validation groups in a SAIL interface is to enable different validation behavior associated with different buttons. This feature allows for more granular control over how user input is verified depending on the action being taken. For example, a form might have a "Submit" button that requires all fields to be validated and complete, while a "Save Draft" button might permit saving even when some fields are incomplete. By grouping fields in validation groups, developers can customize the validation rules that apply when a user interacts with specific buttons, leading to a user-friendly experience that reflects the intended behavior of the application.

The functionality of validation groups thus enhances the interface's flexibility and adaptability to various scenarios, improving usability without compromising on the integrity of the data being submitted.
