44Events in the JVM are by default timed (it's more common)
45Perhaps a little strange. Might change.
46
47EVENTS
48
49Declard with the 'event' tag.
50
51<value fields> can be one or more of
52   value            - a simple primitive or constant type value
53   structvalue      - value is a sub-struct. This type must be previously defined
54                      with 'struct'
55All these require you to declare type, field and label of the field. They also accept
56an optional description of the field. If the meaning of the field is not obvious
57from the label you should provide a description. If an event however is not actually
58meant for end-users, you should probably _not_ write descriptions at all, since you
59might just add more concepts the user has no notion of/interest in.
60
61Events should be modeled after what conceptual process you are expressing, _NOT_
62from whatever data structures you might use inside the JVM for expressing a process.
63
64
65STRUCT
66
67Declared with the 'struct' tag.
68
69Declares a structure type that can be used in other events.
