<DisplayPattern>
   <IfEqual>
      <Expr1>
         <Field Name="CheckedOutUserId" />
      </Expr1>
      <Expr2 />
      <Then />
      <Else>
         <HTML><![CDATA[ <a href="]]></HTML>
         <HttpVDir/>
         <HTML>
            <![CDATA[ /_layouts/[%=System.Threading.Thread.
               CurrentThread.CurrentUICulture.LCID%]/UserDisp.aspx?ID=
            ]]></HTML>
         <Field Name="CheckedOutUserId" />
         <HTML><![CDATA[ ">]]></HTML>
