 However, information is sparse. The syntax encoding schemes {{{dcterms:W3CDTF}}} and {{{dcterms:ISO639-3}}} do exist according to [http://dublincore.org/documents/dcmi-terms/ DCTERMS], but an up-to-date opinion about how to use syntax encoding schemes is difficult to obtain. The proposed recommendation [http://dublincore.org/documents/2008/09/01/dc-ds-xml/ 2008 XML Guidelines] uses {{{dcterm:date}}} only like this:
 {{{
-<dcterms:date>2005-05-05</dcterms:date>
-<dcterms:date rdf:datatype="http://www.w3.org/2001/XMLSchema#date">2005-05-05</dcterms:date>
+B.17:  <dcterms:date>2005-05-05</dcterms:date>
+B.18:  <dcterms:date rdf:datatype="http://www.w3.org/2001/XMLSchema#date">2005-05-05</dcterms:date>
 }}}
-Any suggestions?
+
+Each example in [http://dublincore.org/documents/2008/09/01/dc-ds-xml/ 2008 XML Guidelines] comes in three versions. The three versions of example 18 are:
+
+DC-DS-XML (section 4.5.2.1):
+{{{

+DC-Text syntax (appendix A.18):

+Now what?
 
 2. Should we rename our {{{<metadata>}}} element? In all examples it is {{{<ref:Description>}}}. However, in most examples it seems to mean the repository version of the metadata, not the version in the xml file itself.
