SPEC SECTION:

[http://dev.w3.org/html5/spec/text-level-semantics.html#the-img-element The img
element] [1]

BUG DESCRIPTION:

In the img section, as recommended by WAI CG's Consensus Resolutions on Text
alternatives in HTML 5", please explicitly state: 

"For guidance on accessibility requirements for text alternatives authors
should consult WCAG 2.0." 

Make sure that the text "WCAG 2.0" in that statement links to
http://www.w3.org/TR/WCAG20/ 

OUTCOMES OF FIXING THE BUG:

* Refers people to the WAI's Web Content Accessibility Guidelines 2.0 (WCAG). 
Accessibility is WAI's domain and specialty. WAI develops guidelines which are
widely regarded as the international standard for Web accessibility [2]. WAI's
WCAG defines how to make Web content more accessible to people with
disabilities.[3]

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

* As one study indicates, users prefer embedded reference links into the body
of a document instead of lumping them all into one section. They believed that
embedding the links within a document made it easier to navigate, easier to
recognize key information, easier to follow the main idea of the passages, and
promoted comprehension. [5]

* Could help in the goal of modularizing W3C documents[6] as some information
in the img section may be covered in WAI documents. It may aid in alleviating
duplication of effort and double maintenance.
