Overview

Procedures and best practices for making existing PDF documents accessible.

Table of Contents

Acrobat tags: 

<TOC>
 |
 +-- <TOCI>
 |    |
 |    +-- <Reference>
 |         |
 |         +-- <Link>
 |              |
 |              +-- Tag: Link - OBJR
 |              +-- TOC item label
 |              +-- TOC item leader
 |              +-- TOC item page number
 +-- <TOCI>
 |

The elements of each table of contents line (label, leader, page number) should be broken out into separate tags to control the document flow.

Footnotes

It's not possible in the PDF 1.7 spec to target elements with links. The best that can be done is to target a page within the document. This might change with PDF 2.0.

The superscript element referencing a footnote should be tagged `<Reference>.

The footnote content should be tagged <Note>.

In the tags pane, the <Note> element should follow immediately after the <Reference> tag. This is not ideal, but it's the best option considering the PDF 1.7 spec. This way the footnote has some context. Any other placement will leave it out of context relative to the <Reference> element.

<Note>` tags must have unique ids. (with the tag selected > right click > Properties (Ctrl+I) > Object Properties modal dialog > Tag tab > ID)
