This has been suggested before, and even made it into the spec at one
point, but got removed because there didn't seem to be a way to do
this in a backwards-compatible manner.  There was also the suggestion
of a new element to use for this case, but that appeared late enough
that it's being pushed to "v2" for the moment - html5 already makes a
*ton* of changes and additions to forms.  ^_^
