I've added a type=search input type.

There was a lot of feedback asking for this, but it all basically said 
nothing more than asking for it and sometimes giving a use case. If I 
missed something specific that isn't included below please let me know.

True. Not sure there's much we can do about that here though.

This seems redundant with oninput="" (on the control) and onsubmit="" (on 
the form).

This seems redundant since we have two events for those two cases.

I don't understand why the icon wouldn't always be present.

I don't understand why the UA wouldn't always provide this.

This seems like something we should consider in general for all text 
fields. I'm not sure a domain-specific identifier is the right answer 
though. Isn't the "name" field enough?

The spec requires that of oninput.

Actually it can be a security risk if you can trick the user to click 
(which isn't that hard in practice).

That's not enough of a reason to add it to the spec. :-)

This would be a CSSWG request; please follow up on this with them.

I don't propose to add anything to the spec regarding the autodetection of 
search fields; I don't think we need interop on that particular feature.
