Any news regarding this issue?
We also need to generate PDF/UA document from Microsoft Word documents, for the same reasons: The new law requiring it for all European governments when publishing new pdf documents online.
The law is in effect now, so this is urgent to our customers, and we really hope Aspose.Words could be the solution 
We have moved your post into a new thread. Your thread has been linked to the appropriate issue (WORDSNET-6614) and you will be notified via this thread as soon as this feature is supported. I am afraid, there are no estimates available at the moment. Sorry for the inconvenience.
A possible workaround to convert Word documents to many other formats is as follows:
Document doc = new Document("input.docx");
doc.save("awjava-18.10.pdf");
Document doc = new Document("awjava-18.10.pdf");
doc.convert("file.log", PdfFormat.PDF_UA_1, ConvertErrorAction.Delete);
doc.save("final.pdf");
I tried that, but text is not tagged, and thus cannot be saved as PDF_UA_1
Conversion log entry:
Text object not tagged

As shown above, all text fails as “Text object not tagged”, one error for each letter.
Is there a fix for this?
The same is true for images.

Thanks for writing back.
Currently, PDF/UA Support is on under development stage for Aspose.PDF. We are working over implementing more features regarding image and text tagging inside PDF. We hope soon they will be available in the API for usage.
In the meantime, would you please share you sample PDF document along with complete requirements for making it tagged. This would really help us implementing the functionality accordingly.
In the ideal world, I would like to take any Word document that’s been marked up as well as Word allows (alternate texts on images, links etc. Title defined, tables with header rows defined etc.) and load it into Aspose.Words and save it as a PDF/UA file.
Alternately it would be nice to be able to open the Word document in Aspose.Words, save it as a PDF, then have Aspose.PDF open it and save it as PDF/UA.
This attached file is (according to PAC3) completely PDF/UA approved, except it’s not tagged as PDF/UA.
Yet when I use Aspose.PDF to save it as PDF/UA, I get the following errors in the log:
