Reply To: Illistrative materials, captions and TNs
I would not and can't cite you a reason why, except to say that the blank line would imply that the description did not apply to the illustration. The reason the source citation follows the caption is so that the association between the caption and source is not lost. In Section 9, the focus of the guidelines is on displayed materials and you would need a blank line following the last item in the displayed material which generally would be the source.
