Looking at the [Tasks Involved in Accessibility ](https://www.w3.org/WAI/planning/arrm/tasks/) We don't really describe what these are (types of roles): - [Images and Graphs](https://www.w3.org/WAI/planning/arrm/tasks/#images-and-graphs) - [Semantic Structure](https://www.w3.org/WAI/planning/arrm/tasks/#semantic-structure) - [Input Modalities](https://www.w3.org/WAI/planning/arrm/tasks/#input-modalities) - [Form Interactions](https://www.w3.org/WAI/planning/arrm/tasks/#form-interactions) - [CSS and Presentation](https://www.w3.org/WAI/planning/arrm/tasks/#css-and-presentation) - [Navigation](https://www.w3.org/WAI/planning/arrm/tasks/#navigation) - [Data Tables](https://www.w3.org/WAI/planning/arrm/tasks/#data-tables) - [Animation and Movement](https://www.w3.org/WAI/planning/arrm/tasks/#animation-and-movement) - [Static Content](https://www.w3.org/WAI/planning/arrm/tasks/#static-content) - [Dynamic Interactions](https://www.w3.org/WAI/planning/arrm/tasks/#dynamic-interactions) Or the Role based tasks: - [UX Designer](https://www.w3.org/WAI/planning/arrm/user-experience/) - [Visual Designer](https://www.w3.org/WAI/planning/arrm/visual-designer/) - [Content Author](https://www.w3.org/WAI/planning/arrm/content-author/) - [Front-End Developer](https://www.w3.org/WAI/planning/arrm/front-end/) [The Tasks page](https://www.w3.org/WAI/planning/arrm/tasks/) should have an intro explaining the types and roles a bit more.
