Re: Delete PDF tag vs. artifact?

I think it is preferable to artifact decorative content instead of just
removing the tags: otherwise you may end up with "untagged" content when
you use the built-in automated accessibility checker in Acrobat to check
the accessibility of your PDF. And in some cases, it will mean that you
have content in your PDF content tree that is not placed inside a
declared container, which is required by the more extensive PDF/UA
specification for accessible PDFs.

In practical terms, I'm not sure in which cases this will affect a
particular user of assistive technology, but the best practice would be
to artifact these items.

When you delete the tags in the tag editor, you are not deleting them
from the actual content tree, but just from the tag tree, and screen
readers will use the tag tree to present the content if they can.

I'm not sure of the best practice regarding periods at the end of
alternative text. I normally don't. Unless my alternative text contains
more than one sentence - which I try not to do!

I am testing and find that if I delete the irrelevant tags from the PDF they still display on the PDF but are not spoken by the NVDA screen reader. I am generating PDF tags when I save the MS Word doc to PDF, so as far as I can tell I am not losing my irrelevant images.
