The submission behavior of various browsers I've tested is the following:

Netscape 4:  Hitting enter in a text input submits only if there only one text
input in the form.  The click event on the submit button is not fired, and the
submit button is not successful (in HTML 4 form submission terms).

IE/Win 5/6:  Hitting enter in a text input always submits.  If there is only one
text input in the form, the behavior is as Netscape 4.  If there are multiple
text inputs, the click event on the submit button is fired and the submit button
is successful (effectively, the click triggers the "normal" form submission code
path).

Mozilla:  Hitting enter on a text input always submit.  Behavior is the same as
IE's behavior for the multiple-text-input case -- a click event is dispatched on
the submit button, which triggers submission and causes the submit button to be
successful.

The point is, a number of sites that have forms that have more than one text
input do validation in the submit button's onclick handler instead of doing it
in onsubmit handlers... since said handler is always fired in NS4/IE/Mozilla,
they get away with it.

No idea.  I just followed the link you had to the ISO website and noticed the
status...

Ah, I see.  So the key is that 1970-W01 contains 1970-01-01, not that 1970-W01
is the first week of 1970.  Might be good to make the 1969-W53 example in the
spec to clarify that.

I think this would be clearer if the specification explicitly stated that said
rounding may cause the value to be out of range, thus triggering a rangeOverflow
or rangeUnderflow validation error.

I guess my point is that for number types or step this would be a very difficult
to follow suggestion and that attempts to follow it are likely to be pretty buggy...

It wasn't clear whether "interface" was a "user interface" or a "programming 
interface" (like a DOM interface, say).  The latter interpretation makes it 
sound like the readonly DOM attribute should disappear if the type of the 
control is changed, which I think is not the intent here.

It just reflects the content attribute in Mozilla, and the language the DOM spec 
uses implies that that's what should be happening (the "See the XXX attribute 
definition" phrasing is what the DOM working group uses for "just reflect the 
attribute value into the DOM").
