Description

It would be useful to have a marker interface like the following in the Jackrabbit API:

interface NonExternalEventListener extends EventListener { }

The observation dispatcher could then avoid delivering any external events to that listener.

For backwards compatibility such a listener should still use an "if (!event.isExternal())

{ ... }

" wrapper for event processing. That way the listener can avoid processing external events also when registered with an older repository that doesn't know about this marker interface.
