There are 3 identifiers for domains 

 - ID   - unique amongst all running domains on a hypervisor
 - Name - unique amongst all domains on a hypervisor
 - UUID - unique amongst all domains in a datacenter 

So if you want to track inactive domains, you have a choice of name or
UUID. The recommendation is always that applications use UUID to track
domains internally. Name should mostly be used when interacting with a
user, not for internal application tracking.
