Troubleshooting an accessible pdf that is failing the accessibility checker in XI
I'd appreciate some assistance troubleshooting an accessible pdf that is failing the accessibility checker in XI.
Firstly I'm unsure why this is failing (I've previously made similar documents successfully), and secondly, I've run out of options in trying to repair it.
My pdf (like the others I've done) started out as a long-document book file created in InDesign CS5.5.
My process for creating the tagging, alt text, etc, was done by following instructions in Adobe TV training videos.
I'm getting two errors that I can't repair:
1. the Table of Contents (created in INDD via Table of Contents dialogue box and style sheets)
Error message: Tagged Annotations - Failed
2. For a H3 level heading:
Error message: Appropriate nesting - Failed
I've run the Wizard in Acrobat XI but it couldn't fix the problem. I've rebuilt stylesheets, reimported the table of contents and done any number of adjustments to the InDesign file to try and repair the issue but nothing has worked.
