From the language, I got an impression that assertion is only generated by token service after clients presenting some credentials,
there are may be some cases that "assertion" don't need client's credential.
e.g., Resource owner as a token service  could generate "assertion" to a client he trusts, bu signing a statement that "This delegation is given to a client called clinet-id
for doing something for me".
