Following up on http://drupal.org/node/332980#comment-1123354, the RDFa dtd requires XHTML 1.1. The relevant changes between XHTML 1.0 and XHTML 1.1 are:
# On every element, the lang attribute has been removed in favor of the xml:lang attribute.
# On the a and map elements, the name attribute has been removed in favor of the id attribute.

The themes will have to remove the old lang attribute and only use xml:lang.

A quick grep revealed:

./modules/forum/forum-icon.tpl.php:18:  <a name="new">

There might be more of them and we'll need to fix these as well.

I tried to grep around in various ways to see if there were some l() calls or similar with 'name' => $foo or similar, but found nothing.
