Confirming the nomenclature of services in Solaris

Hello,
I've been revising my course material on Solaris 11 and got to a doubt that I forgot to clarify.
Maybe I can take advantage of you expertise to clear this out.

The material says that the service FMRI is composed of category + name + instance, such as in:
svc:/network/dns/client:default
         |---------------------| |----------|  |-----------|

There's no doubt for the instance which is what follows the ':'.

Is "name" the whole thing or the last portion uniquely identifiable?

Thanks in advance,
Carlos.
