Hi Nicolas,
I like your approach, wouldn't it be great if _all_ browsers
supported the css content attribute...
I think the method should be made available to the formfield because
that allows one use it in the view in different ways; as a class or
extra HTML.
Glad to see I'm not the only one though:-)
Regards,
Marijn
