Vladimir Dzhuvinov:

In a recent spec update `private_key_jwt` authentication at the Trust Mark endpoint was made optional. Previously the JWT `sub` claim was used to determine the Trust Mark subject. Now we are going to need an explicit `sub` parameter to convey the subject, designated as REQUIRED.
