/**
 * @file
 * Default theme implementation for empty spans with RDF attributes.
 *
 * The XHTML+RDFa doctype allows either <span></span> or <span /> syntax to
 * be used, but for maximum browser compatibility, W3C recommends the
 * former when serving pages using the text/html media type, see
 * http://www.w3.org/TR/xhtml1/#C_3.
 *
 * Available variables:
 * - metadata: Each item within corresponds to its own set of attributes,
 *   and therefore, needs its own 'attributes' element.
 *
 * @see template_preprocess_rdf_metadata()

 * @ingroup themeable
