      XML Schema for JSP 1.2.

      This schema is based upon the recent (May 5th, 2001)
      W3C recommendation for XML Schema.

      A JSP translator should reject an XML-format file that is
      not strictly valid according to this schema or does not observe
      the constraints documented here. A translator is not required
      to use this schema for validation or to use a validating parser.
