Really?

I guess the only use case for that would be submitting to different domains.

Taking that successful submit param on the server, all that is needed
is a simple RequestDispatcher.

WF2/HTML5 - Too many new features while there are things in HTML that
still don't work in IE or Webkit.

Opera needs to get some basicthings in order before implementing these
new things. For example:

<form><input name="toString"></form>

javascript:try{ alert(document.forms[0].elements); } catch(ex) { alert(ex); }

Opera: Error: Object doesn't implement [[Call]].

Because Opera tries to call the 'toString' property off of the
'elements' object. It should not do this, but should have an internal
method that safely converts the HTMLCollection to a string.
