IE8b2, WebKit trunk, Firefox trunk, and Opera 9.6 are now all consistent 
and do what the spec says:

   http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E%0A...%3Cform%20action%3D%22..%2F..%2Fcgi%2Ftest-tools%2Fecho%22%3E%3Cbutton%20name%3Da%3Ex%3Cbr%3Ey%3C%2Fbutton%3E%3Cbutton%20name%3Db%20type%3Db%3Ex%3Cbr%3Ey%3C%2Fbutton%3E%3C%2Fform%3E

Thus, I have not changed the spec to match the above requests.
