Structure for reading and navigation
Headings, paragraphs, lists and tables need meaningful tags. They allow people using screen readers and other assistive technology to move through a document and understand its structure.
Reading order and tables
Columns, captions and footnotes need a logical reading order. Table headers must be connected to the cells they describe. The relationships matter as much as the appearance.
Images and language
Meaningful images need useful text alternatives. Decorative elements should be marked as artifacts. The document language and changes of language help assistive technology pronounce the content correctly.
Checks and review
Technical validation can find structural problems. A reviewer also needs to check whether the reading order, descriptions and table relationships make sense. The delivery report records the checks and remaining limitations.
