Simultaneously, it facilitates the tabbing navigation for visual user agents and speech navigation for speech-oriented user agents (related to improving the Accessibility for Web Applications).
Then, the grouping of semantically related controls within a form is an important aspect of providing additional information so users can understand and complete a form successfully. It improves usability and gives support for accessibility.
