Other elements alternate text failed

[janetd30067311]

Hi,

My first time making a PDF with accessibility requirements. So far everything has been really easy to fix but i just can't figure out how to fix this section - other elements alternate text (see photo).. it's the only thing not passed. Appreciate any instructions or advice on how to go about fixing this.. I have tried the 'explain' rule from adobe help but this really isn't making any sense to me either

thank you!

You should use tools that provide more specific guidance, and align with the requirements for tagged PDF as defined in the ISO 14289-1 standard (PDF/UA):

- PAC 2 - PDF Accessibility Checker v2 (free, Windows only, standalone)

- callas pdfaPilot - PDF/UA validation (which is always free/enabled in this otherwise commercial product, Mac and Windows, either standalone or runs as Acrobat Pro plug-in)

- callas pdfGoHTML - diagnostic structure viewer (free, Mac and Windows, Acrobat Pro Plug-in)
