WSE3 unable to DeSerialise ByteArrays on properties?

Hi,
I've recently come across an issue with WSE3 being apparently unable
to de-serialise a property on an object I'm exposting as a WSE3 web-
service in the following way:

private byte[] hashField;


[System.Xml.Serialization.XmlElementAttribute(DataType="hexBinary",
ElementName="hash")]
public byte[] Hash {
get {
return this.hashField;
}
set {
this.hashField = value;
}
}

WSE3 seems capable of Serialising this object out to XML successfully,
but appears unable to DeSerialise the XML back into an object graph,
when I attempt to do this, I'm presented with an exception as follows:

System.Web.Services.Protocols.SoapException:
System.Web.Services.Protocols.SoapException: Server was unable to
process request. ---> System.InvalidOperationException: There is an
error in the XML document. ---> System.NotImplementedException: The
method or operation is not implemented.

Is this the expected behaviour of attempting to De- serialise XSD
hexBin types, or should I be doing something special with my
Attributes?

Many thanks
