recursive nesting

Hi all,

I would like to know if its valid to do recursive nesting( like the pattern shown below) in XML.


<item>
   <item>How are you</item
   <item>I am fine</item>
<item>
<item>
    <item>
         <item>what is your name?</item>
         <item>what is your profession?</item>
    </item>
</item>

Please let me know.

Thanks,
Jack
