[syslog-ng]priority level ?

Hi all, I was wondering.. When I create a filter, if I specify a priority level, for example 'err' does that also imply all facility levels greater than err are also matched ? On the face of it this doesnt seem likely given I'm filter matching, but looking at the syslog-ng.conf.SunOS file in contribs/ and other examples this is what it can only seem to be saying. For example for /dev/console the example filter is { level(err) or (level(notice) and facility (auth, kern)); }; I'm hardly going to leave out everything above err, or notice for auth and kern if I am to send important messages to the console. Thanks for your help, Tony
