Re: Conforming to WCAG 2.0 SC 2.4.5 (Multiple Ways) for pdf files

Hi Janathan

The Techniques are non-normative. The definition of Web Page is normative.
Whenever there is a discrepancy between the Normative and Non-normative
documents, the normative should prevail. Maybe we should file a bug...

>From a best practice perspective I'd always recommend PDF bookmarks, helps
many people including those with cognitive disabilities...

Cheers,
David MacDonald
