The "output" element in WF2 shouldn't really be a new element. The 
semantics and interface are very similar to the input element 
(especially a input type=text with readonly). I suggest changing 
<output> to <input type=output>.
Only important difference is the fallback behavior. An <output> element 
would not be submitted in a non-WF2 UA, an <input type=output> would, 
since it would default to <input type=text>. This is not a big deal, 
though, since we can just avoid giving the field a name attribute.
