EML

Here's a proposed element definition for the /eml/dataset/citation field. I have preliminarily checked this into EML trunk (r2344) for incorporation in the next release. As it is optional and at the end of the dataset fields, it should be fully backward compatible with prior versions of EML.

<xs:element name="citation" type="cit:CitationType" minOccurs="0" maxOccurs="unbounded">
  <xs:annotation>
    <xs:appinfo>
       <doc:tooltip>Data Citation</doc:tooltip>
       <doc:summary>A citation to articles or products in which the
       dataset is used or referenced.</doc:summary>
       <doc:description>A citation to articles or products in which the
       dataset is used or referenced. The citation element contains 
       general information about a literature resource that has used or
       references this dataset resource.
       </doc:description>
    </xs:appinfo>
  </xs:annotation>
</xs:element>
