Joseph Percivall commented on NIFI-5474:
----------------------------------------
Yup, the "embedded" EL in the content being replaced was what I was trying to
convey in the ticket. Apologies if it was unclear.
I'm in the camp of "no embedded expressions". As it's something that isn't
quite intuitive and there hasn't been a need come up for it yet (no feature
requests).
