The xhtml of all normal site pages is unparsable by at least one XML parser (ExPat) because there's no space between attributes in the string border="0"src="http://creativecommons.org/images/public/norights.png" in the html for the Creative Commons No Rights Reserved icon. In other words, the above string should be changed to border="0"src="http://creativecommons.org/images/public/norights.png" The pages validate regardless of this issue, for what that's worth.
Fixed and updated the site. Closing bug!
