This page exists purely for the purpose of trying out commenting. You cannot edit any of the data on this page, but you should be able to leave comments with suggestions on how to extend, or modify, existing text.
Because it is possible that a page has multiple sections with the same name, this page has two such sections - comments made in one section should not end up in the other section's comment area.
This is the second section called 'subsection'.
The commenting system filters quotes (single and double) as well as pointy brackets (< and >), so these should not lead to any problems.
