Hi Fabien

My concern was not with the word "transmission", but with the word
"authority". Per your statement:

" ... except maybe if the token itself allows for delegation (but that's a
really uncommon case, since JWT doesn't allow that, so I don't think people
would even think of it). "

That is the confusion I am concerned about. Someone NOT familiar with what
it does may easily think that the "token allows for delegation" is the
purpose of the protocol as authority is commonly used as a reference to the
entity that can issue assertions, not use assertions.
