Straight from the PDF Support in XPP manual: (page 8-2)

You can use the PDF tagging features of the Direct to PDF (divpdf) program
to help provide people with disabilities, such as vision, hearing, or motor
impairments the ability to access electronic information.
CSS is used to tag the textual content and generate bookmarks/annotations
(links). Output options allow for creating a fully PDF/UA-compliant
document or using CSS to generate bookmarks and annotations only,
without having to tag all the content.
These properties work with both CSS-XML and XML Divisions, provided
that the XML is well-formed and the markup is based on the logical reading
order of the document.

You might wonder why it is limited to XML based documents, but without clear start and end of fragments, trying to output an ADA compliant PDF would always be a very tricky thing. Something that you better say no to from the start

Thanks Bart for the response. I also gone through the manual but just wanted to reconfirm with you guys.

Warm Regards,

That being said, in a non-XML (i.e. Classic Mode) workflow it can be done.

We've seen some customer(s) do it.

But as Bart said it is "very tricky" and all manual coding (using the GEN and RECT type pdfmarks).

Perhaps a customer who had done it and uses this Community might respond with some details.

You might also consider paying someone that's done it already to help you get started if you really need to do this in a non-XML workflow.  

Jonathan,

I have done it once before we had the PDF tags using XPP V8.4  with the GEN pdfmarks and that was for a very simple and fairly rigid XML application.
Yes in the end it did work.(and no, I do not want to do it again)
But there were some fairly tricky things and problems
Don't remember the exact details but I seem to remember (could be wrong) that I ran into trouble with things that got split over pages.
And there were some parts that I could not mark up in enough detail.

In short, I would not recommend it.
