   * URI permanantly assigned to the "xml:" prefix. This is used for some

   * and xml:lang. It was defined by the W3C's XML Namespaces spec.</li>

   * URI which indicates that a name may be an XSLT directive. In most

   * XSLT stylesheets, this is bound to the "xsl:" prefix. It's defined

   * by the W3C's XSLT Recommendation.</li>

   * <li>S_OLDXSLNAMESPACEURL (http://www.w3.org/XSL/Transform/1.0) was

   * used in early prototypes of XSLT processors for much the same purpose

   * as S_XSLNAMESPACEURL. It is now considered obsolete, and the version

   * of XSLT which it signified is not fully compatable with the final

   * XSLT Recommendation, so what it really signifies is a badly obsolete
