+ The <code>longdesc</code> attribute <em class="rfc2119">must</em> contain
+ a <a href=
+ "http://www.w3.org/TR/html5/infrastructure.html#valid-url-potentially-surrounded-by-spaces">
+ valid non-empty URL potentially surrounded by spaces</a>. The URL is a
+ <a href="http://dev.w3.org/html5/spec/links.html#hyperlink">hyperlink</a>
+ to a description of the image that the parent <code>img</code> element
+ represents.
+ </p>
+ <p>
+ The linked description <em class="rfc2119">should</em> be in a broadly
+ accessible format.
+ </p>
+ <p>
+ When a description is only part of the target document, authors
+ <em class="rfc2119">should</em> link to a fragment link in the target
+ document (e.g. <code>longdesc="example.html#description"</code>).
+ </p>
+ <p>
+ Authors <em class="rfc2119">should</em> not rely solely on longdesc where
+ standards exist to provide direct, structured access.

+ <h4 id="fragments">Examples of well-formed, accessible longdesc that also point to fragment links</h4>
+ <p>
+ In a review and verification process of <a href=
+ "http://www.d.umn.edu/~lcarlson/research/ld.html">Laura Carlson's
+ longdesc research</a>, I identified 9 different sites with 48 pages
+ referencing 89 longdesc fragments links (republished below). A quick assessment of the rest
+ of her research revealed at least 13 additional sites, with 48 pages and 73 fragment
+ links.
