Re: Authorized Issuer Lists

+1 — this is why ToIP uses "trust registry". Also, to another point made on
this thread, the ToIP Trust Registry Protocol Specification notes
that trust registries and chained credentials are not mutually exclusive
approaches to verifying the authority of an issuer. In fact they can be
highly complementary; they are just different paths for navigating a trust
chain.
