Actually, the trailing period is typically defined on the item
element, like so:
<item suffix=".">
… which clearly won’t work for the annotated case, which should be:
Doe, J (1999) Title, New York: ABC Books.
Notes notes notes notes notes notes notes
notes notes notes notes notes notes notes
notes notes notes notes notes notes notes.
The trailing period there belongs to the note, and is not added by
the CSL engine.
