Cascade CSP:if

[Nuno Canas]

    <csp:if condition='$l(%request.Get("OBJID"))>0'>
      <csp:if condition='%session.Get("LOGINLEVEL")<4'>
    	<td><img src='../images/trash.gif' ALT='Delete' 
OnClick="if(#server(..DeleteRecord(#(%request.Get("OBJID"))#))#){alert('Deleted');form_new();}else{alert('Error');}"></TD>
	  </csp:if>    	
	</csp:if>    	

Is this supported ??
