== The <code>longdesc</code> microformat, as described in W3 bug 10434 ==

[http://www.w3.org/Bugs/Public/show_bug.cgi?id=10434#c4 Bug 10434] against HTML5, describes how <code>rel="longdesc"</code> could be used to improve the advice found in [http://www.w3.org/TR/WCAG20-HTML-TECHS/G73 WCAG 2.0’s Technique G73]. Hopefully the ideas expressed in that bug, will be taken into this microformat.

Here is a summary of what that bug says: <code>rel="longdesc"</code> allows authors to not only use adjacent links as description links (adjacent links are the only links which WCAG20/G73 suggests being used as ''description links''). <code>rel="longdesc"</code>, in contrast, would permit authors to also use all other link kinds: image maps, placing a link in the fallback of an <code>object</code> element  or even  — voila! — permit authors to '''wrap''' the embedded object in a link. (Can you believe it: WCAG 2.0 does not seem to mention that one can wrap the embedded object in a link element!) With a <code>rel="longdesc"</code> link, one should not even need to use 1 pixel wide images as a way to hide description links (yes, hiding links in "a small image" is in fact something which G73 suggestes.)
