For anyone else who runs into this, here's a comment from the top of the Sortable Tables HTML: Technically we should be using this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"; [<!ATTLIST th mochi:format CDATA #IMPLIED>]> However, that will only work if the document is served with a Content-Type of "application/xhtml+xml". Browsers don't parse the tag right otherwise.
