I know that so far (until MSSQL 2005 at least), system databases are master, model, msdb and tempdb.

Thing is, as far as I can tell, this is not guaranteed to be preserved in the future. And neither the sys.databases view nor the sys.sysdatabases view tell me if a database is considered as a system database.

Is there someplace where this information (whether a database is considered a system database or not) can be obtained?
