5.10.2: Accessible content creation Where ICT is, or includes, authoring tool functionality, the authoring tool shall enable and guide the production of content that conforms to clauses 9 (web), or clause 10 (Nonweb documents), or clause 11 (Non-web software) as applicable. NOTE: Authoring tools may rely on additional tools where conformance with specific requirements is not achievable by a single tool. For example, a video editing tool may enable the creation of video files for distribution via broadcast television and the web, but authoring of subtitle files for multiple formats may be provided by a different tool.

Why is it important? • A lot of inaccessibility happens during production of content. • Finding inaccessibility earlier is cheaper. • If the tool can’t do what’s needed, it’s blocking accessibility.

How to test? (Enablement) 1. Define type of content that can be created using this tool. 2. For each, list what sort of accessibility is to be expected for that type of content 3. Verify if that accessibility information can be added using the authoring tool. Pass: Feature to add accessibility information is there and works Fail (examples): the user can create a table, but there is no way to add headings the user can create a list but there is no way to mark it as a list the user can add images, but there is no way to add alternative tex the user can add video, but there is no way to add captions
