             <p>A <classname>textlistitem</classname> is a
               <sgmltag class="element" role="lz.listitem"><listitem></sgmltag> which displays text.  This is the most
               common form of a <sgmltag class="element" role="lz.listitem"><listitem></sgmltag>, and is the default
               listitem for <sgmltag class="element" role="lz.combobox"><combobox></sgmltag>s,
               <sgmltag class="element" role="lz.menu"><menu></sgmltag>s, <sgmltag class="element" role="lz.list"><list></sgmltag>s, and
               <sgmltag class="element" role="lz.floatinglist"><floatinglist></sgmltag>s.
