SPEC SECTION: The Guidance for conformance checkers [1] 

BUG DESCRIPTION:

In the conformance Guidance for conformance checkers section allow
role="presentation" on img. It is important to be able to convey
programmatically to assistive technology that an image is presentational and
not of interest. 


OUTCOMES OF FIXING THE BUG:

* Indicates to assistive technology that these images purely decorative [2]
visual enhancements, decorations or embellishments that provide no function or
information beyond aesthetic to users who can view the images. They have no
meaning in themselves and do not provide page content [3] so they can safely be
skipped.

* Provides a validity option for images that are purely presentational. 

* Is in accord with Accessibility Coordination Group's "Consensus Resolutions
on Text alternatives in HTML 5". [4]
