Re: Netsted lists in W3C's Validation Service (http://validator.w3.org/)

Nested lists should be used in the following format:

<ul>
    <li> . . . </li>
    <li> . . .
        <ul>
            <li> . . . </li>
            <li> . . . </li>
        </ul>
    </li>
    <li> . . . </li>
</ul>


In fact, the example on the W3C page DOES follow this format.  Copy & paste
from that page:

<UL>
     <LI> ... Level one, number one...
     <OL>
        <LI> ... Level two, number one...
        <LI> ... Level two, number two...
        <OL start="10">
           <LI> ... Level three, number one...
        </OL>
        <LI> ... Level two, number three...
     </OL>
     <LI> ... Level one, number two...
</UL>

Notice that none of the <li> elements have closing tags.  The reason that
this is valid is that the ending tags are implied in the correct places.
The following is how the HTML would look if the end tags were included:

<UL>
     <LI> ... Level one, number one...
     <OL>
        <LI> ... Level two, number one... </LI>
        <LI> ... Level two, number two...
        <OL start="10">
           <LI> ... Level three, number one... </LI>
        </OL>
         </LI>
        <LI> ... Level two, number three... </LI>
     </OL>
     </LI>
     <LI> ... Level one, number two... </LI>
</UL>

The reason the "deprecated example" was labelled such is that the omission
of closing tags is no longer considered valid and is only allowed for
backwards compatibility.
