I think that I agree with what Yannick said above and didn't see what I interpreted as a direct answer to the question.  It does seem to me that TRACE_SYSTEM, TRACE_MODULE, etc really are related to domain/scope and not related to levels.  It seems conceivable that I am only interested in seeing TRACE_INFO from the process level scope as opposed to the system level and would like to be able to filter using the domain additionally.  What am I missing?

thanks,
