Is it posible to use NHibernateContrib 1.0.4 with NHibernate 2.0?

I tried. But how to handle the exception:

"<hibernate-mapping xmlns='urn:nhibernate-mapping-2.0'> wurde nicht erwartet."
==
"<hibernate-mapping xmlns='urn:nhibernate-mapping-2.0'> not expected."

Yes, i use "urn:nhibernate-mapping-2.2" (in my nhibernate-mapping.xsd), so "urn:nhibernate-mapping-2.0" seems to be wrong ...
but how to tell the HbmSerializer that he must create an "urn:nhibernate-mapping-2.2"?

Thank, Mike ...

using System;
using System.IO;
using System.Reflection;
using NHibernate.Cfg;
using NHibernate.Mapping.Attributes;

namespace Foo
{
/// <summary>
/// Creates a configuration for NHibernate 2.0 using
/// the annotations of NHibernateContib 1.0.4.
/// </summary>
/// <example>
/// Configuration configuration = Configurator.Configure();
/// ISessionFactory factory = configuration.BuildSessionFactory();
/// ISession session = factory.OpenSession();
/// ...
/// </example>
class Configurator
{
/// <summary>
/// Creates the NHibernate configuation.
/// </summary>
/// <returns>
/// The NHibernate configuation.
/// </returns>
public static Configuration Configure()
{
HbmSerializer.Default.Validate = true;

string xml = BuildXML();
Configuration configuration = new Configuration();
// Use hibernate.cfg.xml to configure <hibernate-configuration>
configuration.Configure();
// Use annotations to configure <hibernate-mapping>
configuration.AddXmlString(xml);
return configuration;
}

private static string BuildXML()
{
string xml = "";

MemoryStream stream = Serialize();
foreach (byte b in stream.GetBuffer())
xml += (char)b;
stream.Close();

xml = xml.Replace("", "");
xml = xml.Replace("urn:nhibernate-mapping-2.0", "urn:nhibernate-mapping-2.2");
return xml;
}

private static MemoryStream Serialize()
{
MemoryStream stream = new MemoryStream();
HbmSerializer.Default.Serialize(stream, Assembly.GetExecutingAssembly());
stream.Position = 0;
return stream;
}
}
}

Simply use NHibernate.Mapping.Attributes-for-NHibernate-2.0.0...
