incorrect attribute of primary link

Ok, so trying to validate my site, I get a validation error for the primary links (no such attribute: description). The attribute should be 'title' not 'description'. I've changed it in phptemplate.engine, function phptemplate_page

changing

$attributes['description'] = $value['description'][$i];

to

$attributes['title'] = $value['description'][$i];

makes my site validate Ok

(sorry, don't have line numbers to hand :)
