Your comment on G134: Validating Web pages:
> Accessibility of PDF is becoming more and more important. The examples
> in this SC are limited to HTML and XML. I feel next updates of WCAG 2.0
> should also give guidance about validating PDF.
> Proposed Change:
> Include an Example 4: Validating PDF.
> Include a section "Validating PDF" (Ressources) and PDF accessibility
> checker (PAC) as a Ressource and also the .Acrobat Accessibility Checker
> (Full Check)

files are not required to contains tags, which are an optional feature of

The PDF Technology Notes,
http://www.w3.org/WAI/GL/WCAG20-TECHS/pdf_notes.html, contains a section on
Accessibility Checking and Repair. We would consider adding resources on
accessibility checking and repair to the PDF Technology Notes
http://www.w3.org/WAI/GL/WCAG20-TECHS/pdf_notes.html. We welcome suggested
resources for this.
