Within bibliographic references and contributor groupings, this element designates unnamed individuals (typically indicated in print with the text “et al.”).
This DTD allows the <etal> element to be treated as empty, that is, the element has no content or to have text content such as “Associates, co-workers, and colleagues”. This rare element is typically used by stylesheets to generate text such as “et al.”“ or “and others”.
