Comment Type: general comment
Summary of Issue: "sections" = "section" in Glossary?
Comment (Including rationale for any proposed change):
In Note 2, it reads "This success criterion covers sections within writing,". We couldn't understand what "sections within writing" means. Does "sections within writing" mean the same thing as "section" in Glossary?

Proposed Change:
Need clarification.
