Notas do Editor

  • Success criteria 1.3.1 Info and Relationships: Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text. (Level A)
  • We want to do the same thing for accessible materials such as textbooks that include text description for images or other access features.
