In most regards, the <input> element treats an empty name the same as the lack
of a name.

This is true for example during form submission, and weather the element shows
up in the form.elements collection.

However, the one exception appears to be that for radio buttons, <input> with
an empty name attribute belong to the same radio group. However elements with
no name attribute belong to no group.


Firefox 3.6 does what the spec currently prescribes.
Firefox 4 puts empty-named radio buttons in no group. (Disclosure, this change
was made by me, though I don't remember if it was an intentional change or not.
It could have been a side effect of some code cleanup).
Webkit puts empty-named radio buttons in no group.

Don't have Opera or IE at hand to try, but [1] indicates that Opera and IE6
behave like Firefox 3.6 whereas IE9 behave like Firefox 4 and webkit.

If this is true the only recent browser that follows the currently specced
behavior is Opera.

To make name handling more consistent I propose that we treat empty-named radio
buttons like nameless radio buttons and make them not belong to a group.
