name is an empty string ("").

The source name is used to identify traces. It can be used by a SourceSwitch to determine if tracing is to occur and by a SourceFilter to determine whether to produce the trace. The default source level is used by an EventTypeFilter to determine if tracing is to occur based on the source level of the message to be traced.
