That's it, as I understand it. Sometimes you get
just the leaf
certificate (which contains a public key used to encrypt KDMs) and
sometimes you also get the rest of the chain so you can see the trust.
And I guess, if the software creating the KDMs is set to follow the certificate chain up,
it could also verify wether the device or company would be DCI compliant, and if there is
no chain leading to such result, it could refuse to create KDMs for specific content (like
main-stream features).
I heard that Cine Cert software does that, effectively preventing the creation of KDMs for
non-DCI approved equipment with that software.
