<logger> or <root> (which is the root <logger>)

Not completely.  These are slightly different concepts, though.  <level> is 
used to set the logger priority where using threshold on an appender 
creates a filter for loggers with certain levels.  The threshold filter is 
useful when defining multiple appenders for a logger or set of 
loggers.  You do the same sort of filtering if you create an appender 
without a threshold filter and use...

<root>
     <level value="info"/>
     <appender-ref ref="myappender"/>
</root>

see above.
