Mary,

since an Event is an PackageableElement, you can add an Event to every 
Package. It's derive attribute "owner" will be determined by the 
Package, to which it was added.

But let me precise your statement: A message represents either an 
operation call or the sendig of a signal (see: SendSignalEvent).
