This sounds less like a modeling problem and more like a trust framework
problem.
It seems like you're looking for some way to convey in the credential that
the 3rd party is authorized by the original issuer to continue issuing
credentials.
Such a thing could be done using the evidence property. The reason others
are bringing up delegation and credential chaining is because those
mechanisms may allow for the delegated authority to be revoked, while
simply providing evidence may be a vector for compromise.
This is why I say it is a trust framework problem. What it comes down to is
the verifier's trust model.
