Re: PDFs: Logical Reading Order and Tags

Š And just to add to this scenario: when I have to use Acrobat¹s Edit PDF
to make a change (e.g. a change to some URL in a link) it seems to totally
screw up the tags all around the change site to some significant distance!
I¹m sure I needn't tell you how frustrating it is to do all the tags work
and then get asked to make some "small edit²! I don¹t know a whole lot
about editing PDFs in Acrobat, but now I am wondering if the fault is not
in my stars but in the product, to twist a famous phrase.
