This version of XHTML provides a definition of strictly conforming XHTML 1.0 documents, which are restricted to elements and attributes from the XML and XHTML 1.0 namespaces. See Section 3.1.2 for information on using XHTML with other namespaces, for instance, to include metadata expressed in RDF within XHTML documents.
hResume is a microformat for publishing résumé or Curriculum Vitae (CV) information [1] using (X)HTML on web pages. Like many other microformats, hResume uses CSS class names to make an otherwise non-semantic XHTML document more meaningful. A document containing resume information could be improved to use hResume without altering the appearance to the browser, making it easy to adopt.
