You use SLDSelect instead of drawfeature.

My code for using the SLD + WFS looks something like:

sldCtrl = new OpenLayers.Control.SLDSelect(OpenLayers.Handler.Polygon,
                                  {
                                         displayClass: 
'olControlSLDSelectPolygon',
                                         layers:mylayer
                                  });
                 sldCtrl.events.register("selected", this, function(e){
                       // application specific code to clean up popups 
etc, and populate propNames, plus fixup SRS in filter if needed goes here.
                      // propNames ONLY contains desired attributes and 
does not include SHAPE
                          wfsProtocol.read({  // wfsProtocol previous create
                             filter: e.filters[0],
                             propertyNames: propNames,
                             callback: processSpatialQuery,
                             scope: strategy
                          });
