Editing Acrobat XI PDF Accessibility Repair Workflow (section)

== Images, charts and formulas ==

=== Images ===

''TK: Assign alternate text to the image, or mark it as an artifact.''

=== Charts ===

''TK: Combine all tagged elements in the chart into one `<nowiki><Figure></nowiki>` tag. Assign alternate text for that `<nowiki><Figure></nowiki>` tag.''

=== Formulas ===

The PDF tag structure doesn't full support markup of formulas and equations in an accessible manner. The reader isn't capable of interpreting mathematical formulas for users of assistive technology. 

With that in mind, formulas and equations should be written out in the shortest and most concise manner in the alternate text enclosed in a `<nowiki><Formula></nowiki>` tag.<ref>[https://www.webaccessibility.com/best_practices.php?technology_platform_id=57 Adobe Acrobat PDF Best Practices for equations], webaccessibility.com</ref>
