    Oh yeah? Let's say that the user if viewing a list the they can 
edit.  Under the current draft, a user with a non-WF2 compliant will 
have to remove the last row if they make changes to any of the 
non-template rows that they want to submit. The server may be able to 
compensate, but if the user doesn't know that, it doesn't really matter.

    Oh, I'm sure there's a way around that...

    <input template="template" type="hidden" value="
      <tr id="row[order]">
        <td>
          <input type="text" name="row[order].product" value="">
        </td>
        <td>
          <input type="text" name="row[order].quantity" value="1">
        </td>
      </tr>
    "/>

    Well...I'll figure it out at some point. :(
