originally posted to w3c-wai-pf (whose archives are member confidential), i am resending this example post, which references the working draft of WAI-ARIA States and Properties dated 30 April 2007, located at: http://www.w3.org/WAI/PF/Group/adaptable/ at the request of the XHTML2 Working Group: PROPOSAL: move the description of the graphic BEFORE the graphic, so that it is crystal clear to readers that the caption and illustration are bound together; for an even stronger visual binding, why not place the caption and graphic together in a containing box? this would simply mean reordering the paragraphs surrounding the graphic moving the following: ---- begin GJR's proposed change --- <style type="text/css"> @media screen { div.caption-and-img { border: medium solid #000099; background-color: white; margin-left: 1em; margin-right: 1em; display: inline; padding: .5em; } strong { font-weight: bold; } } @media aural { abbr.spell { speak: spell-out; } abbr.speak { speak: normal; } acronym.spell { speak: spell-out; } acronym.speak { speak: normal; } strong { pitch-range: 80; stress: 80; richness: 80; } } </style> <!-- ... --> <div class-"caption-and-img" aaa:labelledby="#img1"> <p aaa:owns="#img1"> <strong>Caption for Figure 1.0</strong>: Figure 1.0 illustrates a typical <a href="http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/" >Document Object Model (DOM)</a> [<a href="#ref_DOM">DOM</a>] node. Placed within the <acronym class="speak" title="Document Object Model (DOM)">DOM</acronym> node and the assisstive technology is a box containing the contract provided by the user agent to the assistive technology. This data includes typical accessibility information found in the accessibility <acronym class="spell" title="Application Programming Interface" >API</acronym> for many of our accessible platforms for <acronymn class="speak" title="Graphical User Interfaces (GUIs)">GUIs</acronym> (role, state, caret, selection, event notification, parent/child information, relationship, and descriptions). </p> <p> <img id="img1" alt="The contract model with accessibility API's" src="accessibleelement" style="width: 640px; height: 512px;" /> </p> <p> For more information see the <a href="http://www.w3.org/TR/aria-roadmap/">Roadmap for Accessible Rich Internet Applications</a> for the use of <a href="http://www.w3.org/TR/aria-role/">roles</a> in making interactive content accessible.</p> </div> ---- end of GJR's proposed change --- i obviously can't compare and contrast the caption with the graphic -- as long as the caption contains ALL of the information conveyed by the graphic, preceding the graphic with its descriptor places it in context, not just for those who cannot see it, but for those who may have difficulty processing that that which follows the image is related to the image itself, but who is not using any assisstive technology... note that, since there is no effective "re-use" mechanism for ABBR or ACRONYM i put explicit expansions on uncontained instances of the acronym DOM and the abbreviation API -- in the description, as one never knows at what point a reader is entering a document, so i prefer, until the bugs get worked out of ABBR and ACRONYM expanding the first instance of an abbreviated form the first time it appears in any section of a document (that is, after every header, div or contained caption) the abbreviated form should be expanded at least once... my proposal to the HTML WG upon building a reuse mechanism for abbreviated forms is archived at: http://lists.w3.org/Archives/Public/public-html/2007Apr/0065.html and again in: http://lists.w3.org/Archives/Public/public-html/2007May/0341.html as for my definition of STRONG using CSS in the STYLE section of my example, i cleave unto this practice for the reasons outlined in the following: EM is not synonomous with I, nor STRONG with B: http://lists.w3.org/Archives/Public/public-html/2007May/0380.html Author incentives for accessibility: http://lists.w3.org/Archives/Public/public-html/2007May/1059.html gregory. ----------------------------------------------------------------- ABSURDITY, n.
