How to use xs:date() in an update query?

Question

I cannot test xs:date attributes in an "update" query. In a "select" query, all work fine.
This is the sample schema:
<?xml version="1.0" encoding="utf-8"?>
<!-- Created with Liquid XML Studio 1.0.8.0 (http://www.liquid-technologies.com) -->
<xs:schema xmlns:tns="http://OracleTest" xmlns:xdb="http://xmlns.oracle.com/xdb" elementFormDefault="qualified" targetNamespace="http://OracleTest" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="MyComplexType">
<xs:sequence>
<xs:element minOccurs="0" name="FirstChild">
<xs:complexType>
<xs:attribute name="A" type="xs:string" />
<xs:attribute name="B" type="xs:string" />
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="ID" type="xs:string" />
<xs:attribute name="DateAttr" type="xs:date" />
</xs:complexType>
<xs:element xdb:defaultTable="MyElement" name="MyElement" type="tns:MyComplexType" />
</xs:schema>
This is a sample XML document:
<?xml version="1.0" encoding="utf-8"?>
<!-- Created with Liquid XML Studio 1.0.8.0 (http://www.liquid-technologies.com) -->
<tns:MyElement ID="ID1" xmlns:tns="http://OracleTest" DateAttr="2008-03-14" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://OracleTest http://OracleTest.xsd">
<tns:FirstChild A="a" B="b" />
</tns:MyElement>
If I check the DateAttr attribute in a xquery, it works fine:
select xmlquery('declare default element namespace "http://OracleTest"; collection("/Testing")/MyElement[@DateAttr=xs:date(''2008-03-14'')]' returning content).getclobval() from dual
If I execute an update, like this:
UPDATE RESOURCE_VIEW SET RES = deleteXML(RES, '/oraxdbr:Resource/oraxdbr:Contents/Testing/MyElement[@DateAttr=xs:date(''2008-03-14'')]','xmlns:oraxdbr="http://xmlns.oracle.com/xdb/XDBResource.xsd" xmlns="http://OracleTest"')
WHERE equals_path(RES, '/Testing/test1.xml') = 1
I get the error:
SQL Error: ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00607: Invalid reference: 'date'.
31011. 00000 - "XML parsing failed"
Where is the problem?
Thank you!

Hi,
Correct me if I'm wrong, but didn't xs:date() came with xpath 2.0?
deleteXML supports xpath 1.0 .
XMLQuery supports xpath 2.0.
That's why the error "Invalid reference: 'date'".
what function supports which version read Re: Which version of XPathAnts
