XSD/Schema: Who do I set a default for a date-type element?

[Bernhard Kraft]

If I specify a default value in an .xsd-File like this ...

<xs:element name="element1" type="xs:dateTime" minOccurs="0"
default="2004-02-10T00:00:00.0000000+01:00" />

.... and try to build a dataset with xsd /d Dataset.xsd, i receive an
"value doesn't fit the datatype" error.

I tried already formats like "2001-01-01" or "2000/01/01" with the
same result.
Does someone know the right format?

This is my original file:
<?xml version="1.0" encoding="utf-8" ?>
<xs:schema id="Dataset1"
targetNamespace="http://tempuri.org/Dataset1.xsd"
elementFormDefault="qualified"
attributeFormDefault="qualified"
xmlns="http://tempuri.org/Dataset1.xsd"
xmlns:mstns="http://tempuri.org/Dataset1.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element name="Dataset1" msdata:IsDataSet="true">
<xs:complexType>
<xs:choice maxOccurs="unbounded">
<xs:element name="Table">
<xs:complexType>
<xs:sequence>
<xs:element name="element2" type="xs:string" minOccurs="0" />
<xs:element name="element1" type="xs:dateTime" minOccurs="0"
default="2004-02-10T00:00:00.0000000+01:00" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
