I have built a completely accessible publication using the same process I have used countless times. The only thing I have done differently is import content from Word. The content I imported from Word was completely accessible as well and I mapped the Heading styles I used there to the Paragraph styles used in InDesign. Every image is alt-tagged. Every decorative item is marked as an artifact. Every paragraph style is mapped to a PDF export tag with the appropriate heading level. All headings are used correctly and in the appropriate order. I have no tables.
The Acrobat accessibility checker is making all sorts of wild claims. It's failing all of my alt-tags. It is insisting I have tables and I don't. It's saying I have no tab structure and I do. It says my headings are nested inappropriately.
Is there some nonsense hiding somewhere in this document from Word that is causing this to fail? How do I remove it? This is due tonight and I have used this exact process over and over before without issue. The only thing I did differently was Place content from word directly into the InDesign file.
I rebuilt the entire document and it passes the accessibility checker without issue. I suspect these errors are due to having placed content from Word into my InDesign file (and possibly mapping styles from Word to those used in ID) but I would like to know why this exploded as it did. Thanks!
