The specification defines the required structure and formatting of a document and PDF features that are better suited for accessibility. This specification can also be used to produce documents that achieve W3C's Web Content Accessibility Guidelines 2.0 (WCAG 2.0).

The present implementation (January 2020) checks the following:

- Document title is set.

- Document language is set, or that all styles in use, have the language set.

- All images, graphics, OLE objects have an "alt" text (or title in some objects).

- Tables do not include splits or merges.

- Only integrated numbering is used. No manual numbering (e.g., writing "1." "2." "3." at the beginning of paragraphs).

- Hyperlink text is not a hyperlink itself, and hyperlink is described.

- Contrast between text and background meets the WCAG specification.

- No blinking text.

- No footnotes and endnotes.

- Headings must increase incrementally with no skips (e.g., cannot have Heading 1 to Heading 3, skipping Heading 2).

- Text does not convey additional meaning with (direct) formatting.
