          ("coldesc" . "New Field 1 Description")  
          ("coltype" . "character") 
          ("defaultval" . "Default Value")) 
         ; Define an integer field 
         (("colname" . "NEWFIELD2")
          ("coldesc" . "New Field 2 Description") 
          ("coltype" . "integer") 
          ("defaultval" . 1))

          ("coltype" . "point") 
          ("defaultval" . "4.426217, 7.991379, 1.726213")) 
         ; Define a real field 
         (("colname" . "NEWFIELD4")
