I can't get betwixt to write an attribute that is empty ("").

Here's de .betwixt file:

------------------
<info primitiveTypes=3D"attributes">
    <element name=3D"sso">
        <element name=3D"id">
            <attribute name=3D"src" property=3D"idOrigen" />
            <attribute name=3D"dst" value=3D"cn=3DAuthServer, =
ou=3DDESEIN,
o=3DAFIP, c=3DAR" />
            <attribute name=3D"unique_id" property=3D"idMensaje" />
            <attribute name=3D"gen_time" property=3D"fechaGeneracion" />
            <attribute name=3D"exp_time" property=3D"fechaExpiracion" />
        </element>
        <element name=3D"operation">
            <attribute name=3D"type" value=3D"login" />
            <element name=3D"login">
                <attribute name=3D"entity" property=3D"cuitOrigen" />
                <attribute name=3D"system" value=3D"" />
                <attribute name=3D"username" property=3D"cuitUsuario" />
                <attribute name=3D"authmethod" value=3D"passphrase" />
                <element name=3D"profile">
                    <element name=3D"cuit">
                        <attribute name=3D"number" =
property=3D"cuitUsuario"
/>
                    </element>
                </element>
            </element>
        </element>
    </element>   =20
</info>
------------------

This is the class:

------------------
public class InterconexionSETI
{
	private String idOrigen;
	private String cuitOrigen;
	private String idMensaje;
	private String fechaGeneracion;
	private String fechaExpiracion;
	private String cuitUsuario;
=09
      [...]
}
------------------

This is the mapping rutine:

------------------
StringWriter resultWriter =3D new StringWriter();
BeanWriter writer =3D new BeanWriter(resultWriter);
writer.getBindingConfiguration().setMapIDs(false);
//writer.getBindingConfiguration().setValueSuppressionStrategy(ValueSupp
ressionStrategy.ALLOW_ALL_VALUES);
writer.enablePrettyPrint();

try {
	writer.write(setiBean);
}
catch (IOException ioex) { }
catch (SAXException saxex) { }
catch (IntrospectionException iex) { }
			=09
return resultWriter.toString();
------------------

I get the following xml:

------------------
  <sso>
    <id src=3D"CN=3DDEMO,OU=3DSeguridad Informatica,O=3DCertificacion
2,L=3DCapital Federal,ST=3DBuenos Aires,C=3DAR" dst=3D"cn=3DAuthServer, =
ou=3DDESEIN,
o=3DAFIP, c=3DAR" unique_id=3D"9991" gen_time=3D"1163789407"
exp_time=3D"1163790007"/>
    <operation type=3D"login">
      <login entity=3D"30604796357" username=3D"27281677050"
authmethod=3D"passphrase">
        <profile>
          <cuit number=3D"27281677050"/>
        </profile>
      </login>
    </operation>
  </sso>
------------------

Where the <login> element doesn't include the "system" attribute.

I've tried using the ValueSuppressionStrategy.ALLOW_ALL_VALUES, but I
get the following xml:

------------------
  <sso>
    <id/>
    <operation>
      <login>
        <profile>
          <cuit/>
        </profile>
      </login>
    </operation>
  </sso>
------------------

What am I doing wrong??
