    A CVE number would work for log entries concerning vulnerabilities, but
    doesn't cover other cases. However there's nothing to say that a similar
    definition mechanism couldn't be used for other things.
    
    To take a concrete example, think about a login event. That could be
    generated by an OS login, a network authentication service, a business
    application, many other things. But in each case it is some kind of login
    event, only the details differ. So, should that be treated as event #200?
    Event #200, subtype #3 (UNIX)? Is it 12 different types of event? Or what?
    Can everyone make up their own IDs, or does it need some kind of
    co-ordination and registration?
    
    It's also clear that trying to standardise on even that one type of event is
    a fairly large piece of work that takes you far from home - including such
    issues as how to represent a user ID in various systems. Should that be a
    string? A number (e.g. a UNIX UID)? An NT SID? Kerberos principal name? All
    of the above? Should a user ID be a part of all events, a standard header
    item? What about things like delegation, impersonation and effective user
    ids? If a session is created, should the ID of THAT be logged with related
    events, or should the analyzer have to infer it? What if there is no
    session? And so on...
    
    Cheers,
    Frank
