  <Title> A DSD description of the ArticleML syntax </Title>
  <Version> 0.3 </Version>
  <Author> Anders Møller </Author>
 
  <Doc>
    This example DSD is used in the XML tutorial; see http://www.brics.dk/~amoeller/XML
    Note: the DSD is incomplete (and would benefit from some more Doc description elements)
    Exercise to the reader: fill out the incomplete parts such that the DSD captures all
    reasonable syntax requirements of ArticleML :-)
    This example covers much of the DSD language, however it does not
    illustrate redefinitions or default definitions.
