Severities have lower numerical values the more severe a message is, with Critical = 1 and Verbose = 16 enabling numerical comparison to capture a given severity and worse or better. For example, Severity < LogMessageSeverity.Warning will match Error and Critical. The enumeration values are the same as those used in the .NET Trace subsystem for equivalent severities.
