[syslog-ng] Facility Filter Range

Hi, I thought I must have just messed up some syntax here, but nothing I do seems to work. The issue is with my attempts to specify filter facility function *ranges* - here's the error message (from "syslog-ng -s"): "Error parsing filter expression, syntax error, unexpected LL_DOTDOT, expecting ')' in /etc/syslog-ng.conf at line 69, column 35: filter f_namain { facility(local0 .. local7) and program(namain); }; ..." Filter function specifications like "facility(kern, authpriv, cron)" and "level(warn .. emerg)" appear to work fine. Am I doing something obviously wrong? Thanks, -David PS: This is with version 3.5.4.1.
