Not at all. It's a consideration for the readers of the scenario to
understand what is happening, and nothing in the system has knowledge of
it.
No tagging takes place in my scenario. Instead, only the graph of
capabilities dictate who is able to use the opaque storage capability.
S is just naturally outside the reference monitor, so when B invokes s1
to send the c1 capability, G substitute c0 to c1, and S receive the
opaque storage capability.
Note that G has no knowledge anywhere of the processes in or out of the
reference monitor. It's only because B in the first place asks A by the
way of G that it receives mediated capabilities.

And where is identity based access control needed?
Curiously,
Nowhere man
