deserializing HL7 CCD.xml file to native ClinicalDocument Class object

Question

i'm new to hl7 healthcare domain and was assigned a task of serializing and deserializing CCD.xml file.i have successfully generated the ClinicalDocument class from CDA.xsd schema file using xda.exe tool.But as i tried something like

XmlSerializer superCereal = new XmlSerializer(typeof(POCD_MT000040ClinicalDocument), xRoot);
StreamReader sr = new StreamReader(path);
POCD_MT000040ClinicalDocument doc = (POCD_MT000040ClinicalDocument)superCereal.Deserialize(sr);
sr.Close();

it give an error like "There is an error in XML document (4, 2)." "ClinicalDocument xmlns='urn:hl7-org:v3' was not expected."

Here is my ClinicalDocument Class that is generated using xsd.exe tool

using System.Xml.Serialization;
