I don't know, what these slurs mean, I came up with the following
editiorial items:
1. annotational accidentals
2. ligature brackets [I think they should be here, and not together
with the ligatures]
3. Barock rhythm indication
1 is the same as 6.1, maybe 2 is the same as 6.2 (?), and by the topic 3
is the same as 6.3 .
Suggested accidentals sounds good, but the others I wouldn't call
"suggested", since they are about how to interpret the notes, not an
addition/suggestion by the editor as the accidentals are. So I would go
for:
6.2 Brackets indicating ligatures" or "Ligature brackets"
6.3 Rhythmic Barock notation -- or something the like.
Hopefully this doesn't get now too complicated - I guess issues will
clear up when we are actualy working on that section.
