Re: PDF/UA Matterhorn Protocols - how to use?

Hi Christine,

I find WCAG and PDF/UA hard to understand in terms of wording even after
all these years! WCAG got a bit better the last 3-4 years, but I still find
it not that usable for many...

Basically, download this PDF/UA checker (it was PAC 3). It will guide you
in terms of errors, and then look up the errors online and figure out how
to solve them (there is one Section 508 site that does PAC 2 errors, it has
handy videos)
