Advice on which issues can be solved automatically by clicking Fix is available in online Help. This also provides guidance for manually resolving issues.
4-1 Do all figures and diagrams have alternate texts?
Alternate texts are added to diagrams, tables or images, so that people unable to see the display receive a text description of the element. It should summarize the content and maybe purpose of the element.
Solution: select tagged objects with the Edit Object tool in the Edit ribbon, right click, select Properties, then the Tag panel and enter alternate text.
4-2 Do both parent and any of their children both have alternate texts?
Screen readers cannot read the alternate text for nested elements. For instance, if a top-level (parent) form element has alternate text, it will hide any alternate texts added to form elements that are ‘children’ of that parent.
Solution: be sure your alternate texts are supplied to elements at only one level in a nesting hierarchy.
4-3 Are all alternate texts linked to a screen element?
Make sure that alternate text is always an alternate representation for content on the page. If an element has alternate text, but does not contain any page content, there is no way to determine which page it is on. If the Screen Reader Option in the Reading preferences is not set to read the entire document, then screen readers never read the alternate text.
4-4 Do all document elements have alternate text?
This report checks for content other than figures that requires alternate text (such as multimedia, annotation, or 3D models). Make sure that alternate text is always an alternate representation for content on the page. If an element has alternate text but does not contain any page content, there is no way to determine which page it is on.
4-5 Do any alternate texts hide annotations?
Alternate text must not hide an annotation. If an annotation is nested under a parent element with alternate text, then screen readers will not be able to see it.
4-6 Are all headings in a logical hierarchy?
This rule checks nested headings. When this check fails, headings do not have a logical hierarchy.
Solution: Use the Edit menu to go to Advanced Edit mode and use the Document Map panel to view the heading hierarchy.
