I've used shadowbox with images in an XHTML 1.0 Transitional environment, and the results are wonderful. Now I've updated my site, using html5, and would like to avoid the W3C errors associated with "rel='shadowbox'". I've read that the phrase "rel=" can be replaced with "class=" in shadowbox.js, and a similar replacement made in the html, which clears up the W3C issue. However, I can't find an instance of "rel=" in the js file (version 3.03. What am I overlooking? Thank you.
