Is there a textual representation of SQLServer Error Severity Level?

I am looking for a textual representation for severity levels reported by SQLServer error messages. I found a mapping for the error number (*message_id*):

   SELECT message_id, severity, text FROM sys.messages WHERE message_id = 1205

Does something com开发者_如何学Pythonparable exist for the severity level code or is there some list available that names each severity code? All I found was this categorizing stuff on MSDN that tells me that all codes below 10 are informational etc...

The most comprehensive list I have seen is this MSDN article Database Engine Severity Levels

Although, for severity levels =< 10 it isn't specific but as these informational I don't see this as too much of a issue? The Database engine doesn't even raise these as errors.
