Exported Service provider metadata does not contain X509IssuerSerial details

Hi,
I used following code and a self signed certificate to export service provider metadata.
X509Certificate2 x509Certificate = new X509Certificate2(certificateFileName, (string)null, X509KeyStorageFlags.MachineKeySet);
EntityDescriptor entityDescriptor = MetadataExporter.Export(samlConfiguration, x509Certificate, partnerName);
entityDescriptor.SPSSODescriptors[0].KeyDescriptors[0].Use = “signing”;
entityDescriptor.SPSSODescriptors[0].WantAssertionsSigned = true;

XmlDocument xmlDocument = entityDescriptor.ToXml().OwnerDocument;
using (XmlTextWriter xmlTextWriter = new XmlTextWriter(metadataFileName, null)) {
xmlTextWriter.Formatting = Formatting.Indented;
xmldocument.Save(xmlTextWriter);
}

the created metadata contains
<md:SPSSODescriptor ID=“_44bd1360-c04f-4a52-b261-be6994c15e70” protocolSupportEnumeration=“urn:oasis:names:tc:SAML:2.0:protocol” AuthnRequestsSigned=“false"WantAssertionsSigned=“true”><md:KeyDescriptor use=“signing”>
<KeyInfo xmlns=”“>http://www.w3.org/2000/09/xmldsig#”>

</md:KeyDescriptor>
<md:SingleLogoutService Binding=“urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect” Location=“TODO: URL of SLO service endpoint”/><md:SingleLogoutService Binding=“urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST” Location=“TODO: URL of SLO service endpoint”/>md:NameIDFormaturn:oasis:names:tc:SAML:1.1:nameid-format:unspecified</md:NameIDFormat><md:AssertionConsumerService Binding=“urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST” Location=“TODO: URL of assertion consumer service endpoint” index=“0” isDefault=“true”/>
</md:SPSSODescriptor>

The X509Data tag does not contain X509IssuerSerial informations like X509IssuerName and X509SerialNumber.
Could you please help me to export metadata with required elements.

thanks,
Kaypees.

Currently we do not support the inclusion of these attributes.
How important is it for these to be included?
The issuer is identified in the actual certificate.

Thank you
