Setting a Destination's Threshold
process TEST = {
  service = MessageLogger {
    vstring destinations = {   "detailedInfo.txt"
                             , "critical.txt"
                             , "cout"
                             , "cerr"
                                             }
    PSet critical.txt     = { string threshold = "ERROR"   }
    PSet detailedInfo.txt = { string threshold = "INFO"    } 
    PSet cerr             = { string threshold = "WARNING" }
  }
  untracked PSet maxEvents = {untracked int32 input = 5}
  path p = { myAnalysisModule }
  module myAnalysisModule = ModuleThatIssuesMessages { }
  source = EmptySource { }
}
The string threshold = "WARNING" parameter
in the PSet configuring cerr tells the 
destination writing to cerr to ignore all messages
with severity below WARNING.  Thus messages
issued (after the service has been configured with this .cfg file) 
using LogDebug and  
LogInfo will have no effect on
cerr.
