As instead of adding a few more tags to the list it would be better to allow the user to write in a individual-tag name. For ePub-Tags it is possible. Why not for PDF-Tags?

this would be a necessary function for creating accessible documents!
i miss especially the note-tag

I would think just adding all the tags available from Acrobat into the design software would create a huge win for workflow. Having to go back into the PDF in Acrobat and adjust those tags is a pain point.. especially now if you need to make an edit and re-export the PDF. Please fix this Adobe! :)

@Adobe: any update to this request?

The number of Federal and State Government employees in the U.S. alone that are required to make all documents 508-compliant should be enough to make it a priority to fix accessibility issues in your products. Please accommodate us, just as we have to accommodate our readers.

I work in health care and we are required to make our documents 508-compliant and accessible. This would save a lot of time when designing a document.

Ditto what Bevi said. The tags available, particularly when mapping styles to tags, is not sufficient to produce PDF/UA deliverables.

Yes!!!

I want this feature.

We need to set the block-level entities of the PDF/UA-1 tag set in InDesign. Right now we have a skimpy choice of headings, <P>, and Artifact. We need these other available in the Export Tagging style definition:

Block-Level for Paragraph Styles:
<BlockQuote>
<Caption>
<Note>

Inline Character Level for Character Styles:
<Artifact>
<BibEntry>
<Code>
<Formula>
<Quote>
<Reference>
<Span> (yes, folks, we sometimes need this *&^%$ tag)

And Container/Grouping tags (document-level tags)
<Part>
<Art> done now through Articles panel, but need option to designate it manually
<Sect>
