SLF4J must not be tied to any particular implementation. There is no 
misunderstanding about that. I just had not seen

public class EventLogger {

   .... omitted code

   public static void logEvent(EventData data) {
     if (eventLogger.instanceofLAL) {
       ((LocationAwareLogger) eventLogger.logger).log(EVENT_MARKER, FQCN,
           LocationAwareLogger.ERROR_INT, data.toXML(), null);
     } else {
       eventLogger.logger.error(EVENT_MARKER, data.toXML(), data);
     }
   }


In light of the above, requesting that the LocationAwareLogger.log
method admit an argumentArray parameters makes sense. Given that there
are implementations of the LocationAwareLogger interface outside
slf4j.org, I don't think the LocationAwareLogger interface can be
changed lightly. However, the issue certainly merits a bugzilla
entry. Ralph, may I ask you to enter a bugzilla bug report in relation
with this topic? TIA.
