Why are DomainEvents wrapped into Notifications into Ap layer ?

[LukasKuchta]

Hi, why is ther this concept? Wrapped one into another ? Domain event can be handled directly in App layer. Something what i overlooked?

example:

OK. I found the explanation on the Kamil's blog. There are two kinds of events

1. one is handled inside the same transaction like aggregat's operation
2. outside the transaction. Public event / Domain notification. In the same strasaction like aggregate is only save those events into persistenat layer.
