<h3>The XML Schema Built-in Datatypes</h3>
- <p class="issue">XML Schema 1.1 added a number of new datatypes:
- <code><a href="http://www.w3.org/TR/xmlschema11-2/#dateTimeStamp">xsd:dateTimeStamp</a></code>,
- <code><a href="http://www.w3.org/TR/xmlschema11-2/#dayTimeDuration">xsd:dayTimeDuration</a></code>,
- <code><a href="http://www.w3.org/TR/xmlschema11-2/#yearMonthDuration">xsd:yearMonthDuration</a></code>, and
- <code><a href="http://www.w3.org/TR/xmlschema11-2/#precisionDecimal">xsd:precisionDecimal</a></code>.
- Some of them are already used in RIF and OWL2. They should possibly be added
- here as well. Also,
- <code><a href="http://www.w3.org/TR/xmlschema11-2/#duration">xsd:duration</a></code>
- is noted below as being unsuitable for use in RDF. The design of the type
- has changed, so this should be reviewed. This is
