Remove Specific Namespace from XML file while serialization

Hi Dude,

I am getting extra unwanted namespace while serializing object to XML like

<CalculationInput xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" detailed-errors="true" request-id="1" >

I want to remove only

xmlns:xsd="http://www.w3.org/2001/XMLSchema" from the XML/CalculationInput element.

Please assist me how to achieve

Thanks
