All Deskphone user guide content we create must comply with Section 508 for people with disabilities. Following these standards ensures compliance and avoid a lot of added work later.
The following standards are not specific to DITA content but are required for all source formats:
You must include an alt tag with ANY image and figure elements to make the intent of the image accessible for users using screen readers or text-only readers. Ensure that the text you include in the alt tag provides a complete description and does not restate the name of the image.
You must include the name attribute with any objects elements to make the intent of the object more accessible for users using screen readers or text-only readers.
You must include heading rows in all tables and simple tables.
Avoid creating complex table layouts that include horizontal and vertical cell spans when possible.
