:)

I use it to pass a string that defines the type for notifications that are 'dynamic', so then observers can tell what my intention is depending on current state of the application.

The type parameter can be used as a discriminator to allow a mediator or command instance that has been notified determine if it really needs to take action. This can help reduce the overall number of notification names in the system.

Joel, I like that usage - it removes some of the guesswork, especially if several developers are involved. I actually thought that's what the parameter's intention was (going from the name too) but then saw other examples that worked in a different way.

Cliff - I understand what you are saying. At the moment it's a little hard for me to see the benefit as it just seems to increase the knowledge you need to have about each notification. I guess it's a matter of providing thorough documentation.

cheers - Nils.
