38   * 1700 - 1799 kernel anomaly records
39   * 1800 - 1899 kernel integrity events
40   * 1900 - 1999 future kernel use
41   * 2000 is for otherwise unclassified kernel audit messages (legacy)
42   * 2001 - 2099 unused (kernel)
43   * 2100 - 2199 user space anomaly records
44   * 2200 - 2299 user space actions taken in response to anomalies
45   * 2300 - 2399 user space generated LSPP events

47   * 2500 - 2999 future user space (maybe integrity labels and related events)

49   * Messages from 1000-1199 are bi-directional. 1200-1299 & 2100 - 2999 are
50   * exclusively user space. 1300-2099 is kernel --> user space
