The test takes a while to run. 001.htm doesn't work in Opera, and
001-opera.htm doesn't work in IE7. In Firefox you'll get the "heavy script"
dialog; just press "continue".

Results:

IE7 drops the following attributes:

   <a href>
   <area href>
   <input src>
   <iframe src>
   <img src>

Opera drops a whole lot of attributes. Here's for the <a> tag only:

   <a accept charset class id onkeypress onkeydown onkeyup onclick
   ondblclick onmousedown onmouseup onmouseover onmousemove onmouseout
   onmousewheel onerror onload onresize onscroll onunload onreset onsubmit
   onblur onchange onfocus oninput onselect accessKey action archive
   autocomplete axis background char charset cite classid code codeBase
   codeType cols content data dateTime dynsrc encType face for headers href
   hreflang http-equiv label language longDesc name profile prompt rel rev
   rows scheme scope src standby summary target useMap value valuetype
   version wrap xmlns>

Firefox and Safari don't drop any attributes.
