              The eml-literature module - Citation specific
              information
            </title>
            <para>
              The eml-literature module contains information that describes
              literature resources. It is intended to provide overview
              information about the literature citation, including title,
              abstract, keywords, and contacts. Citation types follow the
              conventions laid out by
              <ulink url="http://www.endnote.com">EndNote</ulink>,
              and there is an attempt to
              represent a compatible subset of the EndNote citation types.
              These citation types include: article, book, chapter, edited
              book, manuscript, report, thesis, conference proceedings,
              personal communication, map, generic, audio visual, and
              presentation.  The "generic" citation type would be
              used when one of the other types will not work.
            </para>
            <para>
              The eml-literature module, like other modules, may be
              "referenced" via the &lt;references&gt; tag.  This
              allows a citation to be described once, and then used as a
              reference in other locations within the EML document via its ID.

        <doc:description>The citation element contains general information
        about a literature resource that is being documented, or a piece of
        literature that is being cited in support of a given resource, such as
        a dataset. It contains sub-elements that are specific to a literature
        resource such as a book, a journal article, a thesis, etc. It extends
        the generic resource elements with literature specific
        fields.</doc:description>
