There is a use case for hierarchical progress elements: e.g. multiple
file uploads (or multiple phases).  Consider the following example:

<progress id="p" max="17" value="5" data-units="MB">
  <progress id="current-file-progress" max="2">1</progress>
</progress>

could be displayed something like this:
<style> div {margin:0;padding:0;height:20px;float:left;} </style>
<div id="p" style="width:170px;background-color:red;">
    <div id="p-prog" style="width:50px;background-color:green;"></div>
    <div id="current-file-progress"
         style="width:20px;background-color:yellow">
        <div id="f-prog"
             style="width:10px;background-color:#00FF00"></div>
    </div>
</div>
