[XXE] spacing between list items

[Rishi Khan]

When I make an itemized list (in a DocBook 5 document) in XMLMind, it  
creates the following type of code:
<itemizedlist>
         <listitem>
           <para>Item 1</para>
         </listitem>

         <listitem>
           <para>Item 2</para>
         </listitem>

         <listitem>
           <para>Item 3</para>
         </listitem>
       </itemizedlist>

1) How to I make it not put in the <para></para> in the <listitem> tags?
2) It seems that if I manually remove the <para></para>, the HTML  
output changes appropriately, but the PDF output does not. Do you  
know why?
