"dateTimeStamp" Datatype Values and Representations

This section describes the built-in primitive datatype, 'dateTimeStamp' that represents moments of time in Gregorian calendar. Leading and trailing whitespaces are allowed and trimmed. Timezone offset is required.

"dateTimeStamp" is a built-in datatype derived from "dateTime" datatype introduced in XSD 1.1 to represent a moment of time in the Gregorian calendar system with these rules:

To verify these rules, I wrote this simple XSD document that uses "dateTimeStamp" datatype to declare XML elements:

<?xml version="1.1"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<!-- dateTimeStamp_datatype_test.xsd
 - Copyright (c) 2013, HerongYang.com, All Rights Reserved.
-->
<xs:element name="DateTimeStamp_Datatype_Test">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="DateTimeStamp" type="xs:dateTimeStamp" 
         maxOccurs="unbounded"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>
</xs:schema>

Here is a sample XML document that can be used to test these declarations:

<?xml version="1.1"?>
<!-- dateTimeStamp_datatype_test.xml
 - Copyright (c) 2013, HerongYang.com, All Rights Reserved.
-->
<DateTimeStamp_Datatype_Test>

<!-- 4 valid "DateTimeStamp" elements -->
  <DateTimeStamp>    1971-05-16T00:00:01Z    </DateTimeStamp>
  <DateTimeStamp>    1971-05-16T00:00:01.123456780000Z</DateTimeStamp>
  <DateTimeStamp> 345671971-05-16T00:00:01Z    </DateTimeStamp>
  <DateTimeStamp>    1971-05-16T00:00:01+00:00   </DateTimeStamp>

<!-- 3 invalid "DateTimeStamp" elements -->
  <DateTimeStamp>    1971-05-16T00:00:01    </DateTimeStamp>
  <DateTimeStamp>    1971-05-16-05:00</DateTimeStamp>
  <DateTimeStamp>    00:00:01+00:00   </DateTimeStamp>
</DateTimeStamp_Datatype_Test>

Since "dateTimeStamp" is introduced in XSD 1.1, I need to use my Xsd11SchemaValidator.java program presented earlier in the book to run the test:

c:\Progra~1\Java\jdk1.7.0_07\bin\java 
   -cp ".;c:\local\xerces-2_11_0-xml-schema-1.1-beta\xercesImpl.jar;
   c:\local\xerces-2_11_0-xml-schema-1.1-beta
   \org.eclipse.wst.xml.xpath2.processor_1.1.0.jar"
   Xsd11SchemaValidator 
   dateTimeStamp_datatype_test.xsd dateTimeStamp_datatype_test.xml
