what's up with the different notations ?

> I had some troubles with system event listeners added by the following tag handlers:
> org.apache.myfaces.view.facelets.tag.composite.InsertChildrenHandler
> org.apache.myfaces.view.facelets.tag.composite.InsertFacetHandler
> org.apache.myfaces.view.facelets.tag.jsf.core.EventHandler
> As they are no StateHolders, are not serializable and do not have a no-argument constructor,
they cause troubles with state management. The simplest solution would be to make them serializable
but I think it should also be possible to make them transient as the view is rebuilt anyway
on every request. This would generate no state but I'm not 100% sure if there are any side
effects by making the listeners transient (it works for me and I can't think of any currently).
