Re: Acrobat Accessibility Check vs. PAC 3.0?

I'm slow getting back to this, but thanks for the additional info Bevi,
and especially for the explanation of possible use cases where correct
Label <Lbl> tags can make a difference.

In one recent document that was giving me troubles, I marked the bullet
as a figure and inserted the word "bullet" as the "actual text" property
for some standard dot bullets that were not passing the Acrobat Pro DC
checker cleanly. This improved the screen reader experience (by making
it identical to the experience of a bullet that was properly encoded)
while at the same time getting rid of the Acrobat error.

And I have taken a similar approach with incorrectly encoded checkboxes
and alternative text using the phrase "empty checkbox" or "selected
checkbox". These edge cases would probably be better with correct
characters and embedded fonts, I am sure.

Phil.
