Boolean Deserialization Error

I am having problems with deserializeation for an XML element, I am assuming it is something to do with the namespace in the XML element not being found by the deserializer.

The data is coming form an outside source, which I cannot modify as a string and I am using C# 4.0.

Any help, gratefully appreciated.

string xml = "<boolean xmlns=\"http://schemas.microsoft.com/2003/10/serialization/\">false</boolean>";

var xSerializer = new XmlSerializer(typeof(bool));
using (var sr = new StringReader(xml)) 
using (var xr = XmlReader.Create(sr))
{
    var y = xSerializer.Deserialize(xr);
}

Error:

System.InvalidOperationException was unhandled by user code
  HResult=-2146233079
  Message=There is an error in XML document (1, 2).

It will work if you create your serializer as below

var xSerializer = new XmlSerializer(typeof(bool),null, null, 
                         new XmlRootAttribute("boolean"), 
                         "http://schemas.microsoft.com/2003/10/serialization/");

You can't use xml namespaces and attributes if you want to deserialize a boolean. Infact you have to deserialize this:

string xml = "<boolean>false</boolean>";
