Need your help for an issue in Castor VO-XML Mapping file

I am trying to Map VO-XML for the following root tag in XML mapping file

<xtvd from="2005-09-23T06:40:20Z" to="2005-09-24T06:40:20Z"
xmlns="urn:TMSWebServices"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:TMSWebServices E:\VISDP\epgtests\tmsxtvd.xsd"
schemaVersion="1.3">


And I am getting the following error...I tried with ns-uri, ns-prefix,
QName-prefix attributes in <bind-xml> tag, but was not successful....any
help from the team....

org.xml.sax.SAXException: The namespace associated with the prefix: 'xmlns'
is null.
