dates have to have the "T" in it, for the W3C profile of ISO 8601

the first 3 date elements validate, the last does not

<?xml version="1.0" encoding="UTF-8"?>
<test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="C:\temp\xml\testDate.xsd">
  <date value="1997-07-16T19:20:30Z"/>
  <date value="1997-07-16T19:20:30+01:00"/>
  <date value="1997-07-16T19:20:30"/>
  <date value="1997-07-16 19:20:30+01:00"/>
</test>

under this schema:

<?xml version="1.0" encoding="UTF-8"?>
<!--W3C Schema generated by XMLSPY v5 rel. 2 U (http://www.xmlspy.com)-->
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified">

  <xs:element name="date">
    <xs:complexType>
      <xs:attribute name="value" type="xs:dateTime" use="required"/>
    </xs:complexType>
  </xs:element>

  <xs:element name="test">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="date" maxOccurs="unbounded"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

</xs:schema>


so we will standardize on that. You should reference this document in
any documentation:

http://www.w3.org/TR/NOTE-datetime

this section of catalog spec will be updated:
