Review comment:
I would point out this modification as an actual change in logical flow.
From the code, it appeared that the intention here was to include `else if`
rather than just `if`, but if that is incorrect, I can revert this change
(putting the `if` on a new line). An `else if` here prevents empty strings from
being added to the `transitiveAreas` Set; otherwise, an empty `section` String
would result in both `"<root>"` and `""` being added to this Set.
