Can XmlSerializer deserialize into a Nullable<int>?

<?xml version="1.0" encoding="UTF-8"?>
<entities xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="array">
  <entity>
    <id xsi:type="integer">1</id>
    <name>Foo</name>
    <parent-id xsi:type="integer" xsi:nil="true"/>

public static void FixNilAttributeName(this XmlNode @this)
{
    XmlAttribute nilAttribute = @this.Attributes["nil"];
    if (nilAttribute == null)
    {
        return;
    }

    XmlAttribute newNil = @this.OwnerDocument.CreateAttribute("xsi", "nil", "http://www.w3.org/2001/XMLSchema-instance");
    newNil.Value = nilAttribute.Value;
    @this.Attributes.Remove(nilAttribute);
    @this.Attributes.Append(newNil);
}

xmlStr = Regex.Replace(xmlStr, "nil="true"", "xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"");
