Might change. 4141N/ADeclard with the 'event' tag. 4141N/A<value fields> can be one or more of 4141N/A value - a simple primitive or constant type value 4141N/A structvalue - value is a sub-struct. This type must be previously defined 4141N/AAll these require you to declare type, field and label of the field. They also accept 4141N/Aan optional description of the field. If the meaning of the field is not obvious 4141N/Afrom the label you should provide a description. If an event however is not actually 4141N/Ameant for end-users, you should probably _not_ write descriptions at all, since you 4141N/AEvents should be modeled after what conceptual process you are expressing, _NOT_ 4141N/Afrom whatever data structures you might use inside the JVM for expressing a process. 4141N/ADeclared with the 'struct' tag. 4141N/ADeclares a structure type that can be used in other events. 4141N/A has_thread="true" is_instant="true">
