Form composed of Panel components

[Chris Colman]

I have a complex form that I choose to break down into logical sub Panel
components and then add them as children to the Form.
 
The sub Panels themselves then have FormComponents like text fields and
DropDownChoice components added to them. Will the normal validate/update
mechanism simply work like that or do I need to override some methods in
my Panel classes or make the Panel classes implement certain interfaces
(eg., IFormVisitorParticipant etc.,)?
