           Summary: provide an introduction to wai-aria in the wai aria
                    section of the spec
           Product: HTML WG
           Version: unspecified

as the editor suggests in his change proposal 

"Add an introductory paragraph that explains what ARIA is before using
the acronym. The exact text is left to editor discretion, but it
should include an expansion of the acronym, an explanation of the
purpose of the technology, and could include an example."

the information provided to authors about wai-aria is lacking.

here is an example of the sort of information to provide


The Web Accessibility Initiative Accessible Rich Internet Applications
(WAI-ARIA) Suite, defines a way to make Web content and Web applications more
accessible to people with disabilities. It especially helps with dynamic
content and advanced user interface controls developed with Ajax, Dynamic HTML,
JavaScript, Cascading Style Sheets, and related technologies. Currently,
certain functionality used in Web sites inaccessible to some users with
disabilities, especially people who rely on screen readers and people who
cannot use a mouse. WAI-ARIA addresses these accessibility challenges by
defining new ways for functionality to be provided to assistive technology.
Desktop operating systems have long provided APIs to allow assistive technology
products to access applications, by exposing the role of a control along with
its states, properties, and values. WAI-ARIA allows web application developers
to expose the same sorts of information for Web applications. This information
is used by user agents to support the same accessibility APIs as used by
desktop applications allowing authors to provide accessibility information
consistent with their intent. With WAI-ARIA, developers can make advanced Web
applications accessible and usable to people with disabilities.

Authors often use a combination of scripting, event handlers, and CSS to create
custom widgets. When there are native language features that provide the same
semantic meaning and interaction behaviors as a custom widget, authors are
strongly encouraged to use the native language features. In these cases,
accessible user agents should have done most of the work to ensure these native
language features support assistive technologies. If the author chooses to
create a custom widget, thus changing the functionality of an existing HTML
element, the author may need to add WAI-ARIA role and aria-* attributes to make
it accessible. In these instances the author must follow the conformance rules
for applying WAI-ARIA to HTML defined in this section as well as the rules for
using WAI-ARIA defined in the [WAI-ARIA] specification."
