It would be helpful if annotations such as comments and footnotes/endnotes were connected to the paragraphs they describe.
Some possible approaches:
1. Use accessible relations. In particular:
a. The described-by relationship could be added to the paragraph. This relationship would have as its target the comment or footnote/endnote.
b. The description-for relationship could be added to the comment or footnote/endnote. This relationship would have as its target the paragraph being described.
2. Implement accessible hypertext/hyperlink support for comments and footnotes/endnotes. In particular:
a. The superscripted indicator for footnotes/endnotes would be treated similar to a link insofar as accessible hypertext/hyperlink is concerned. ATs like Orca would then implement the navigation between the paragraph and its annotation.
b. Something similar would need to be done for comments. But since comments seem to have an insertion offset rather than a range, I'm not sure what the best approach would be. Perhaps the start index and end index could both be the value of the character offset?
