I agree with that observation. In addition, reading the section in
context, how would people feel about "PDF File Production and
Accessibility" - it's nice and neutral (ie: makes no assumptions about the
levels of accessibility PDF supports, and allows for progressive
enhancement as the technology improves in a11y support) and it (from a
technical document point of view) better describes the section in that the
section doesn't actually tell you how to how to do something or describe a
process (as is inferred by the current heading or Shawn's suggestions)
rather it talks about production and and associated accessibility tools in
the abstract sense.

Again agree - also I do find it kind of weird that a) checking and repair
is considered separate to production b) that Acrobat Pro isn't listed with
the tagged PDF tools and c) isn't repair by inference suggesting that it
has the ability to change content and therefore author?

So I would suggest either "Authoring Tools which can be used with the
Sufficient Techniques: ((link to the ST's), and then sub group these into
editing and tagging tools, and checking tools. Even better - create a
matrix of tools and the functions they support to avoid needless
duplication.

How about: "PDF includes several features in support of accessibility of
documents to users with disabilities. The core of this support lies in the
ability to determine the logical order of content in a PDF document,
independently of the content's appearance or layout, through logical
structure and Tagged PDF. For this reason, producers of PDF files must
ensure that all information in a document is reachable by means of the
structure hierarchy. In doing so, assistive technologies can be used to
present PDF to users in the much the same manner as they would access
other formats such as HTML markup or document files."

ie: the focus isn't on the type of technology (or disability) rather than
the standardization of the user experience across readable formats. This
in a sense is the spirit of the discussions there have been around moving
back to a more general technology agnostic approach - in these tech notes
I feel the inference is that structural hierarchy in any content is a
"good thing" for accessibility, which is how it should be.

Agree

Has anyone used this tech on the list? Or is it vendor claims?
