The PDF Techniques Accessibility Summit will identify best-practices in tagging various cases in PDF documents. Questions to be addressed will likely include: the legal ways to tag a nested list, the correct way to caption multiple images, the appropriate way to organize content within headings.
My hospital emailed me a medical records release form as a PDF. They told me to print it, fill it, sign it, scan it and return it to the medical records department, in that order. In 2018? To get the form via email (i.e., electronically), yet be asked to print it? Did the last 20 years just… not mean anything! So I thought I’d be clever. I’d fill it first, THEN print it. Or better yet, never print it, but sign it anyhow, and return it along with a note making the case for improving their workflow. The story continues…
The PDF Association recognizes its members supporting ISO 14289 (PDF/UA)! Members offering PDF/UA services are also recognized.

Organizations listed in italics are not members of the PDF Association but are included in this listing because they are either assistive-technology providers or developers of free open source software, with products that offer at least partial support for tagged PDF and PDF/UA.
The ability to create tagged PDF documents with semantically-appropriate structure elements from a source file or existing untagged PDF.
The ability to create PDF documents conforming to PDF/UA (ISO 14289-1:2014).
The ability to correct the logical structure tree of a tagged PDF file.
The ability to confirm PDF/UA conformance based on the Matterhorn Protocol‘s set of checks:
|P||Partial, some limited aspects of verification|
|M||All machine checks. Without human verification, machine verification is usually inadequate.|
|Complete validation, all checks (machine and human).|
The product includes an end-user-oriented interactive PDF (or PDF-alternative) viewer that uses tagged PDF to make PDF/UA files available to Assistive Technology.
