I believe the intent of deployed element is of a physically (at least 
on a computer or in real life) existing thing. I originally called this 
a deployed resource.

Deployed elements include services, also agents, also descriptions. 
They also include application frameworks, firewalls, etc. etc., but 
these are out of scope.

Essentially, you can only manage something that exists. Its also true 
that, for mgt purposes, what the managed thing does is kind of 
unimportant - management is at the meta-level: you want to have 
descriptions of the managed resource, and you want to be able to turn 
it off (say), but interacting with a service as a service is different 
to interacting with the same computational resource from a life-cycle 
perspective.

It is certainly true that not all services and/or agents need to be 
managed. I think the diagram could use correction about that.
