I see that would be a problem.

So I took a step back, and realized that including people and how they 
already interact around BSc and so forth may be a red herring.

The system being designed here should function equally-well if a 
machine is being given a credential (for being able to be safe, or do 
a certain job) -- and a machine might even make that decision, and a 
database might be the final user.

So here's another radical change. How about looking at it from the 
point of view of evidence and statements about evidence. I'll use A, 
B, and C as the actors. Can be people or machines, any of them.

A brings evidence to B. B considers the evidence and decides to issue 
a credential -- the evidence is satisfactory.  At this point:

B declares a credential.
B is a Declarer.

B issues the credential to A to use.
A is a Bearer of the credential.

A takes the credential to C.
C is an Acceptor of the credential.

Thus, Declarer, Bearer, Acceptor.
