Serialize XML fragment using namespace using C #

Question

I'm having trouble deserializing the following XML fragment (from OneNote):

<one:OE creationTime="2015-03-21T18:32:38.000Z" lastModifiedTime="2015-03-21T18:32:38.000Z" objectID="{649CA68C-C596-4F89-9885-1553A953529E}{30}{B0}" alignment="left" quickStyleIndex="1" selected="partial">
    <one:List>
        <one:Bullet bullet="2" fontSize="11.0" />
    </one:List>
    <one:T><![CDATA[Bullet point one]]></one:T>
</one:OE>

The following code is used to deserialize the above snippet. The OE class has the following attributes:

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.34230")]
[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://schemas.microsoft.com/office/onenote/2013/onenote")]
[System.Xml.Serialization.XmlRootAttribute("OE", Namespace = "http://schemas.microsoft.com/office/onenote/2013/onenote", IsNullable = true)]
public partial class OE : EntityBase<OE>
{
    ...
}

And the actual fragment deserialization method is in the EntityBase base class:

public static T Deserialize(string xml)
{
    System.IO.StringReader stringReader = null;
    try
    {
        stringReader = new System.IO.StringReader(xml);
        return ((T)(Serializer.Deserialize(System.Xml.XmlReader.Create(stringReader))));
    }
    finally
    {
        if ((stringReader != null))
        {
            stringReader.Dispose();
        }
    }
}

The deserialization method is called the following:

var element = OE.Deserialize(xmlString);

If the variable xmlStringis the above XML fragment. When calling the method, DeserializeI get the following error:

There is an error in XML document (1,2). ---> System.Xml.XmlException: 'one' is an undeclared prefix. Line 1, position 2.

I spent some time looking for attributes declaring namespaces in the OE class, but everything seems to be correct. Can anyone point out the error I'm making?
