To add to what Christoph is saying, perhaps there's a better way to look at this problem? A reverse list has both a start and an end, just like any other list. The key is that it's displayed in the opposite order of a regular list.<br>
<br>This raises the question, why does the list need to be <i>serialized</i> in reverse order? Given that it's a display attribute, wouldn't it make more sense to force the UA into rendering the list in reverse? e.g.:<br>
<br><div style="margin-left: 40px; font-family: courier new,monospace;"><ol style="order: reverse;"><br><li>one</li><br>
<li>two</li><br>
<li>three</li><br>
<li>four</li><br>
<li>five</li><br></ol><br></div><br>Which would then render like this:<br><br><div style="margin-left: 40px;">5. five<br>4. four<br>3. three<br>2. two<br>1. one<br></div><br>This also solves the partial render problem as the list would partial render as follows.<br>
<br>Step 1:<br><br><div style="margin-left: 40px;">1. one<br></div><br>Step 2:<br><br><div style="margin-left: 40px;">2. two<br>1. one<br></div><br>Step 3:<br><br><div style="margin-left: 40px;">3. three<br>2. two<br>1. one<br>
</div><br>Step 4:<br><br><div style="margin-left: 40px;">4. four<br>3. three<br>2. two<br>1. one<br></div><br>Step 5:<br><br><div style="margin-left: 40px;">5. five<br>4. four<br>3. three<br>2. two<br>1. one<br></div><br>
Obviously this solution puts a bit more of the onus on the User Agent to render the list correctly, but I think it's semantically more correct than trying to encapsulate the display data in the DOM ordering. This also provides backward compatibility as UAs that don't understand the reverse attribute will still number the list correctly. (Whereas the previous solutions would result in the numbering being reversed in older browsers.)<br>
