 In Mapserver 5.0 SOS support has been upgraded to use a new metadata called sos_procedure_item. The value for sos_procedure_item is the field/attribue name  containing the procedure values. The use of this metadata as well as the sos_procedure is described here per type of request (refer to http://trac.osgeo.org/mapserver/ticket/2050 for more description):
 
+It should be noted that, for very large datasets defined only with sos_procedure_item, this may result in costly processing, because MapServer has to process attribute data.  It is advised to setup and manage datasets accordingly if dealing with large observation collections.
